  1. Good to know. I do have ECC memory installed. What is the purpose of the file integrity plugin then if it just shouldn't happen anymore?
  2. Yes and that's fine but SSDs are not slower when they're part of the cache instead of unassigned I would assume, unless BTRFS makes them slower than xfs somehow.
  3. This might be off topic a little bit but are you suggesting Plex is faster on an unassigned SSD than on a SSD cache? I just want to make sure that I'm not missing out on something crazy, I have a RAID1 cache SSD and did notice an improvement over HDDs but if it's faster completely outside the array/cache...
  4. Hi, First of all, I want to thank everyone in this community working on making unRAID such an awesome product. I just had a disk fail on me 2 days ago and I swapped it for a brand new one with almost no downtime at all, the GUI made me feel safe during the whole process of rebuilding the disk from parity and I really appreciate knowing my data is very safe in the future (with backups too just in case ;-)). My question is regarding silent data corruption, also known as bit-rot. I've read a little bit about it on the unRAID forums and over r/unraid on Reddit and did notice the existence of the Dynamix File Integrity plugin below. However, while this plugin, well configured, will help me detecting any potential issue, it doesn't fix the issues. Two years ago, someone was asking a similar question (https://www.reddit.com/r/DataHoarder/comments/537ys9/unraid_users_how_do_you_handle_disk_encryption/), and I see comments saying the devs at LT were considering adding some sort of protection against bit-rot, because if well integrated it could be fixed on-the-fly thanks to the parity disks. Years later I don't see many discussions regarding this and I'm sure it's an important subject to a lot of us data hoarders. Am I missing something or do we still have in 2019 to address this issue completely manually (ie. by restoring backups when it happens and hope the backup isn't corrupted and is up-to-date enough)? If there is anything about this coming soon in unRAID that I'm unaware of, I'd definitely like to hear about it!
  5. I'm also interested in this question since most motherboard manufacturers have provided updated version of their BIOS following Spectre. If it's at the motherboard level then how can the OS interact with this? There is definitely a detail we're missing here.
  6. well somehow sr0, sda, sdb and sdc weren't counted in this specific case.
  7. Really, floppy and optical drives count? I'm lucky I don't have old hardware, that would be a huge issue lol. I mean if you add the BMC virtual medias you can have 5 or 6 completely empty media drives...
  8. I've never seen a keyboard be counted as a device when it comes down to unRAID licensing. I have the basic license with 6 HDD and it wasn't an issue despite the 3 "Unknown USB devices" identified as sda, sdb and sdc.
  9. It's probably just relevant to my OCD ;-). And obviously because I'm monitoring my VMs with check_mk, it doesn't really like the letter change.
  10. You are actually 100% right. Seems like the floppy was indeed created by the BMC setting but the 2 other USB peripherals were me on the IPMI console. Heh... well, the problem is now solved, thank you. It's basically a mixed of the 2. I wasn't connected to the console when I did a reboot earlier... then the issue was there so I went into the BIOS through the console and just made it worst by staying on the console while rebooting couple more times. Then I found the virtual media settings on the BMC which made one of the 3 drives disappear permanently but the 2 other ones would stay. After I closed the console they both disappeared. I wonder if unRAID could handle this differently a little bit, like prioritize hard drives over USB devices when it comes to device assignment (except maybe for the boot drive which is sda). It would solve most possible issues.
  11. 10+ reboots later the virtual floppy went to sdh instead of sdb. Considering I usually reboot 3-4x per year, I'm done testing for a couple of months. But really, it sucks. ASUS says to enable the power saving mode to have the drives disappear and all it really does is making them disappear then reappear randomly. It seems that somehow I managed to boot and have unRAID see the disks as sdb sdc etc before the floppy but it's weird.
  12. I'm so confused. (big thanks to... ASUS... lol https://www.asus.com/support/FAQ/1012437/) Setting all 3 to 0 make 2 of the 3 devices disappear, then 1 reappears again. After a reboot I now see 2 instead of 3.
  13. I don't have anything on the only PCIe port. I have 2 USB peripherals, one being the boot USB flash drive (in the internal USB port) and the other is my UPS. Nothing else attached other than 3 RJ-45 to the 3 ports. The 6 internal SATA ports are used.
  14. I don't have any "virtual floppy" (or floppy setting) in my BIOS and it's not consistent across reboots, ie. sometimes they're not there. Still, here are some screenshots from the BIOS just in case.
  15. I just checked and everything I need is in the BIOS so I'll go with the SmartFan options (with a more agressive profile than default). Can't say the BIOS is the most user friendly but it works. I'll keep an even more aggressive version of the settings within the plugin so that I can enable it if I'm doing anything crazy.
  16. Hi, After a fresh reboot, I see this: My first HDD starts at sde so it's kinda annoying. I've fixed it in the past by not having any Windows VMs. Annoying, again, and the win2008R2 VM I currently have I do need. I obviously don't have any floppy disks on that VM nor anything special in the XML as far as I know (it does it pretty much with any version of Windows installed in any VM but maybe it's just random and I'm going crazy). Here are diagnostics. I've had this issue for months if not years, currently on the latest unRAID version. Any help would be greatly appreciated. I see this in syslog: Jun 10 15:01:54 server kernel: scsi 2:0:0:0: Direct-Access AMI Virtual Floppy0 1.00 PQ: 0 ANSI: 0 CCS This would be the problem. But why is it there? /dev/sdb: Unknown USB bridge [0x046b:0xff40 (0x100)] /dev/sdc: Unknown USB bridge [0x046b:0xff31 (0x100)] /dev/sdd: Unknown USB bridge [0x046b:0xff31 (0x100)] USB bridge? I have a UPS hooked up to a USB port but I really don't think that's the issue. Even the virtual CDROM (sr0) shouldn't be there...
  17. I'd need to take a look at the BIOS options again but last time I checked only the CPU fan would go faster according to CPU temps, not the chassis fans. The issue I have is I need to reboot to get to the BIOS in the first place, whereas with a software plugin such as yours I can edit settings on the fly.
  18. All right well I changed my non-PWM S12b for a F12 (can't go wrong staying with Noctua) and it works (and it's also a huge improvement, I have an ITX case with restricted airflow). Question 1) I was wondering, is there any disadvantage of having a lower temperature polling time value? 3 minutes seems kinda slow, if my CPU is idle and suddenly has a big encoding workload I definitely don't want it to wait 3 minutes until the fans adjust. I was thinking of 30 seconds. Question 2) If I manually set up speeds according to CPU temperatures, does it completely ignore HDD temperatures? Question 3) Any performance disadvantage of using the plugin instead of whatever the BIOS/BMC would do by itself? As in, is there a dedicated chip on the motherboard that would usually do that instead of using CPU resources (assuming your plugin does in fact use the CPU to poll the temperatures).
  19. Potential solution: I assume the /boot/config/share.cfg is loaded in RAM so editing it there without restarting the array doesn't quite fix it completely for newly created shares. I assume.
  20. Hotfixed the mounted share by editing the fsid directly into /boot/config/shares/*.cfg files. However if I create a new NFS share it takes the fsid 101, no matter what I have in /boot/config/share.cfg. There must be something somewhere else?
  21. It seems like they have the same ID. root@server:~# exportfs -v /mnt/user/backups <world>(rw,async,wdelay,hide,no_subtree_check,fsid=100,anonuid=99,anongid=100,sec=sys,insecure,root_squash,all_squash) /mnt/user/discord <world>(rw,async,wdelay,hide,no_subtree_check,fsid=100,anonuid=99,anongid=100,sec=sys,insecure,root_squash,all_squash) /mnt/user/qbittorrent <world>(rw,async,wdelay,hide,no_subtree_check,fsid=101,anonuid=99,anongid=100,sec=sys,insecure,root_squash,all_squash) How is that possible? can it be fixed without deleting the share and/or rebooting?
  22. All right, this is extremely weird. root@server:~# showmount -e Export list for server: /mnt/user/qbittorrent * /mnt/user/discord * /mnt/user/backups * Tested from multiple CentOS VMs, if I mount /mnt/user/discord, it actually mounts /mnt/user/backups. However, if I mount /mnt/user/discord/something, it correctly mounts the discord sub-folder. I've seen weird things but this... What I've tried: restarting the NFS service, rebooting the VMs, manually mounting the NFS vs using /etc/fstab, disabling the discord NFS share and reenabling it... that doesn't work. What works however is disabling the backups NFS share. If I disable it, without even having to umount /mnt/user/discord, it now correctly points to the correct directory. If I enable the backups NFS share again? /mnt/user/discord mounted on my VM now points on the backups share. I'm so confused. Have you ever seen something like that? Is there some sort of file on unRAID I can see more info about NFS share configuration?
  23. Does this plugin support non-PWM fans? Since you can still control their speed through voltage usually. My regular fan speed is detected at 700 rpm (silent mode in BIOS) but the auto-configuration doesn't see it. I have an ASRock Rack board.
