Using the no-op true command on other paths to that disk, will cause GEOM to re-”taste” the disk and see the label and automatically add the additional paths to the existing multipath. This will write a GEOM Multipath label to the last sector of the disk. Each SAS Expander will present as a new /dev/ses# device, so your system may have more than one.

Constant HDD noise -> how to stop it?

If your system has multipath SAS, each disk will be present more than once, and you should use the gmultipathcommand to deduplicate your disks and for labeling as well. FreeBSD supports a number of different ways to label the disk, depending on your use case. The map command displays all of the SES devices and each element (this is the nomenclature in SES) connected to them. Of course, all of this chassis management technology isn’t very effective without tools to make it usable. It also provides information about each slot in the enclosure (even if empty), including a flag to indicate if the device has recently been swapped.

• Its primary purpose is to grant bidirectional remote access between personal computers and mobile devices.
• My Seagate Exos enterprise drives make almost 0 noise actually.
• Unnamed devices can be specified by their specific SES device and element number.
• Of particular note, WD Green drives ship configured to park the heads after only 8 seconds of inactivity which could notionally wear out the disk in a matter of months if the heads are cycling more-or-less continuously!
• Simply installing the apps and choosing a pool for k3s and docker creates a dataset and logs.
• SAS disk reservations provide the ability to connect to the disk redundantly—or even across multiple machines—while ensuring it is only used by one of them at a time.

For ZFS users, automating fault responses with tools like ZED (ZFS Event Daemon) can simplify disk replacement and minimize downtime. Configuring your system to notify you when a disk has errors, or when the filesystem reports a degraded device, will ensure your system gets prompt attention when something goes wrong. Experienced enterprise storage managers also keep extensive notes including the model number, SKU and/or URL for reordering, purchase order information, warranty end date, warranty URL, and any other useful information about each drive. While the operating system typically provides device aliases based on the disk’s serial number, WWN, or some other static identifier, this does not provide all of the information you might want.
Whether you are a computer technician in charge of technical support or a student who needs to work together with their classmates, AnyDesk is the program you are looking for. Then, click on “Connect” to access the other device. Send it to the other user who has the program and they will be able to access and control your device. It is very popular among professionals who provide technical support. Remember, the key is to act quickly and use the right tools for your specific situation. These practices and tools should give you a solid starting point for recovering your deleted files.
In this case, there are at least two disks that I probably need to configure, since /dev/sde seems to be parking as often as about every 4 minutes (0.004 Hz) and /dev/sdc is only parking slightly less often. The smartmon_load_cycle_count_value metric seems like it would be the right one to query, but that actually expresses a percentage value (0-100) representing how many load cycles remain in the specified lifetime- on reaching 0 the disk has done a very large number of load cycles. It does support reading arbitrary metrics from text files written by other programs with its textfile collector however, which is fairly easy to integrate with arbitrary other tools. These communities are filled with knowledgeable individuals who can offer more personalized advice and help you navigate the complexities of long-term data storage.

What is AnyDesk and what is it used for?

I moved my Scale server into the next room, laundry room, just so it’s out of sight. Replacing the drive is financially out of the question. I’m looking for a software solution, if possible, to make the HDD idling for most of the time when there is no load. Yeah, it’s not helping, thanks. Although it’s empty, so this is probably not the source of the constant HDD noise.
When it comes to long-term data storage, there are several strategies and media types that Redditors recommend. It refreshes the disks SMART information every 5 min. ZFS and Btrfs both aim to modernize storage by combining filesystems and volume management, but… Monitoring and maintaining your storage media is one of the most important parts of keeping your data safe.
Other interfaces for remote storage include iSCSI, Fiber-Channel, Infiniband, RoCE, and others, but those specialized solutions are beyond the scope of this article. Serial Attached SCSI (SAS) is the most common interface for enterprise storage, first appearing in 2004. Serial ATA (SATA) is the familiar interface used for non-enterprise storage, and is an extension of the original ATA interface dating from the 1980s. In this article we will discuss some strategies and tools to make managing disk arrays on FreeBSD (and related platforms like TrueNAS Core) much easier. It may be what you want is to enable HDD standby, which will “spin down” the drives when not in use

Understanding Storage Protocols

It’s hard to imagine why your drives are that loud! It’s a datacenter drive, very loud, so it’s still audible. For quietness, a noise reducing case, move it somewhere else, quieter drives, maybe SSD instead of hard drives, etc.

• What causes the constant load on the disk?
• Agree, I have used SeaChest with good results for this same issue on scale plus drive cache.
• Unparalleled PerformanceOur proprietary video-codec, DeskRT, compresses image data to reduce bandwidth and latency to a level imperceptible to the human eye.
• For chassis with larger numbers of drives, or when connecting external JBOD chassis, it is common for the drives to connect to a specialized board that provides power and routing for the SATA/SAS signals to the controller.
• Has anyone found a tool that can use EPC to change the Idle_b and Idle_c values for Exos drives?
• You can also reboot, and GEOM will pick up the multipath when it first tastes the disks during boot.

SATA disks plugged directly into the motherboard use an interface called AHCI which does not provide much in the way of advanced management features. For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard. Non-Volatile Memory Express (NVMe) is a newer storage interface that is becoming very popular for flash storage devices. Just download the executable file on both devices and run it to open the tool. At a glance, changing idle3 and EPC settings seems to have done the job nicely; here is the same graph of head park rates per disk as before, but on a smaller timescale that makes individual head parks visible. Seagate provide a “Seachest” collection of tools for manipulating their drives, but rather more usefully to users of non-Windows operating systems like Linux they also offer an open-source openSeaChest.
This will activate the fault LED for element 9 (Slot 08) on the first SES device. You can avoid any uncertainty by enabling the “locate” or “fault” LED for the drive you mean to replace. This example creates a new GPT partition scheme on da36, creates a 4 GiB swap partition aligned to 1 MiB boundaries, and then adds a ZFS partition with the label e3s01-ZGY0XH87 using the remainder of the space on the disk.
Below we will discuss exactly how to do this with FreeBSD’s sesutil or the management tools for your HBA. Though a truism, it bears emphasizing that with a little planning, management and maintenance of storage systems can be made easier and safer. The total throughput possible from the connected disks is still limited by the number of lanes available, but this is likely the best approach in systems with more than a dozen disks.

My question is – is there a way to tell if a certain disk suffers from the issue prior to purchasing? For the system I’m monitoring here, the SSD that it boots from has a wearout indicator sitting on 95 of 100 (only 5% of the rated life consumed), visibly unchanged for a long time so it’s not very interesting as an example. (The properties like ID_SERIAL_SHORT can be queried on a running system using udevadm info, such as udevadm info /dev/sdd to get the properties of the disk currently assigned ID sdd.) Somewhat more useful for monitoring is the smartmon_load_cycle_count_raw_value, which provides the actual number of load cycles that have been done. Secondly what are your disk monitoring refresh intervals and what do you use on your system to monitor SMART disk health?
The APM specification dating from 1992 includes some controls for hard drives, allowing a host system to specify the desired performance level of a disk and whether standby is permitted by sending commands to a disk. In addition to the above query types, SES also supports a number of commands, including activating the “locate” and “fault” LEDs if present, and the ability to individually power off drives. The first step is to map out the relationship between the physical chassis where the disks reside, and reveryplay the logical devices enumerated by the operating system.
I agree to receive your newsletters and accept the data privacy statement. Ensure device health & easy replacements with these valuable tips. Discover strategies to manage disk arrays on FreeBSD and related platforms/operating systems. Simply installing the apps and choosing a pool for k3s and docker creates a dataset and logs. Your pool gets writes from somewhere and ZFS is writing those to disk every 5 seconds.
Unnamed devices can be specified by their specific SES device and element number. This greatly reduces the chance of getting it wrong when you (or the datacenter technician) physically pulls the disk. You can also reboot, and GEOM will pick up the multipath when it first tastes the disks during boot.

Truenas Scale disk activity every few seconds when idle

Once you’ve done so, you must test delivery to your “real” inbox—you don’t want to learn that delivery isn’t working after your storage has already become unavailable! If you’d feel safer with a team of experts monitoring your storage, consider a ZFS Support Subscription. If you rely on manually checking on your storage periodically, you will regret it. Another important aspect of managing your storage system is configuring notifications. Klara recommends embedding these details directly into the ZFS vdev properties of each disk—a feature Klara created, which will become generally available in the upcoming OpenZFS 2.2 release. In these configurations, your system may or may not support features like individual “locate” and “fault” LEDs.
I noticed that even when doing nothing, I hear the sound of drives working every few seconds. I gave up and just built a Windows Storage Space with tiering and the drives are now effectively silent. I guess it depends on the drives, but don’t think you’ll find any software solution. My Seagate Exos enterprise drives make almost 0 noise actually. The system is never idle really, it’s a server. What causes the constant load on the disk?
