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?

- 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.
- 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?
- I gave up and just built a Windows Storage Space with tiering and the drives are now effectively silent.
- The parking rate basically drops to zero at the time I updated the settings for the Seagate drives, and the Western Digital one hasn’t changed because it needs to be powered off to change that setting and I haven’t done so yet.
- This will write a GEOM Multipath label to the last sector of the disk.
- Disk vendors typically provide their own vendor-specific ways to do persistent configuration of power management settings, so it’s worth trying to use those instead so the desired configuration doesn’t depend on the host system applying it, instead being configured in the drive (but in some cases it might be desirable to have the host configure that!).
- 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 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.

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.
Obligatory word of warning – mucking with low-level drive settings like this can cause issues. Has anyone found a tool that can use EPC to change the Idle_b and Idle_c values for Exos drives?

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. reveryplay 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.
Direct Attached deployments require a bit more hardware and cabling. The NVMe interface is also extensible to allow operating over the network (where it is known as NVMe Over Fabric or NVMe-oF). NVMe on the other hand, supports multiple queues (often 64 queues, but the official specification allows for up to 65,536 queues) allowing for many commands to be run concurrently. While both SATA and SAS allow multiple commands to be issued at once to the device, these commands cannot actually be executed concurrently—instead, they are queued for sequential operation.

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.
I set power mode to Idle and advanced power management to the lowest setting (1) which should spin down the disk after 5 mins. Hello,Like many users of Seagate Exos drives, I have found that they park their heads very aggressively, approximately every 2 minutes. AnyDesk allows you to establish remote desktop connections between devices and opens up unprecedented possibilities of collaborating online and administrating your IT network. Its primary purpose is to grant bidirectional remote access between personal computers and mobile devices. To do this, both devices must have the program installed and must allow access through the use of security keys. The current settings for a disk can be queried with the –showEPCSettings flag.

- Below we will discuss exactly how to do this with FreeBSD’s sesutil or the management tools for your HBA.
- On my system, this command produces a bright red LED lit for that slot, physically highlighting the correct drive to replace.
- NVME-oF allows storage devices and arrays in remote chassis to be connected to local motherboards.
- Unfortunately, APM settings don’t persist between power cycles so if we wanted to change disk settings with APM they would need to be reapplied on every boot.
- Your pool gets writes from somewhere and ZFS is writing those to disk 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.
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.
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.
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.
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).
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.
