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.
I moved the system dataset to the boot pool. I don’t move any data, no apps are running, this is a vanilla Scale install so far, yet the HDD is in constant work. 1 SSD to boot and 1 HDD to store data. Agree, I have used SeaChest with good results for this same issue on scale plus drive cache. If you do it on a live pool, I’d back up your data first.

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 reveryplay source of the constant HDD noise.

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.

While I have been aware of this in my home server as well, it is easy to forget to ensure that disks are not silently killing themselves by cycling the heads. With modern, especially Enterprise grade hard drives being able to have hundreds of thousands of head park operations in their service life, is this really an isssue? With the tools presented here, the reader is well armed to react to failed disks and ensure that the wrong disk isn’t accidentally pulled. However, if a disk has died entirely, or a slot is empty, it might not have a device name. Sesutil can also be used to locate the disk in the physical array.While the SES data tells us that there is an 8 TB disk in Slot 06, it does not tell us which slot in the chassis corresponds to 06. Looking at a few items from the output, we can see the device names (/dev/da0 and /dev/da7 respectively) of the disks in Slot00 and Slot07.
We can also see that the disk in Slot07 was recently swapped, and that Slot08 does not contain a disk and its locate LED is activated. SES provides a mechanism to query information from the enclosure, including temperature, fan speed, and status of power supplies. Many backplanes include support for SCSI Enclosure Services (SES).
- I had this same problem, using HGST data center refurb drives.
- 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.

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.
At somewhat larger scales, a number of drives can be connected directly to a SAS (or SATA) controller PCIe card. But, if the number of ports on the motherboard is sufficient to your needs, this is the easiest way to connect the drives to the system. We are going to focus on some of the most popular for SATA and SAS drives.
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. When building a storage system, there are many different ways the disks might be connected to the system. NVME-oF allows storage devices and arrays in remote chassis to be connected to local motherboards. NVMe storage comes in many form factors, from small M.2 devices to U.2 and other hot-swappable formats intended for servers. NVMe connects storage devices directly to the PCIe bus, offering extremely low latency and high throughput.
- Since I use Prometheus to capture information on the server’s operation however, I can use that to monitor that my hard drives are doing well.
- FreeBSD supports a number of different ways to label the disk, depending on your use case.

I will optimize settings later for the security/quietness tradeoff however, I’m very pleased with it for now. How can I set this value on the Truenas interface? Keeping it spinning but not accessing data is safer. I would still recommend against idling your drive as that reduces longevity. I also set the tunable vfs.zfs.txg.timeout to a somewhat large value so the regular syncs don’t happen every 5 seconds.
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.
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.
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?
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
