Unassigned Devices - Managing Disk Drives and Remote Shares Outside of The Unraid Array

When mounting the array, this is displayed at the bottom panel:

Warning: Use of undefined constant luksKeyfile - assumed 'luksKeyfile' (this will throw an Error in a future version of PHP) in /usr/local/emhttp/plugins/unassigned.devices/include/lib.php on line 584

 

Nothing serious, but should probably be updated soon :) 

 

Unraid 6.7.0 with current Unassigned plugin.

I haven't touched either server since posting this and tried to get the issue to reoccur and upload diagnostics. Everything now seems to be working perfectly, no stuttering, Emby's transcoding buffer stays between 2 and 3 minutes, UD shows accurate size/used/free information. My thought was that maybe SMB or NFS was giving up, and UD might have been involved. In any case, hopefully it doesn't happen again, but if it does I'll upload diagnostics as soon as. Cheers!

Hi all, this is a followup to my original post here of UD "dropping out" and showing 0B with my mellanox connectx-2 NICs. It's continued over the past few weeks intermittently. I've attached diagnostics from 3 occasions, the most recent being today, each set being downloaded a minute or so after Emby (or Plex) started stuttering and UD showed 0B.

Been reading through pages of this stuff...

 

Noob to Unraid here. 6.7.0. I want to mount my Windows ReFS drive on my Unraid server to copy over my media folders, etc. I see it in the Unassigned Devices list, but when I click on Mount, it thinks for a second, and then shows Mount again rather than Unmount, so it seems like it isn't successfully doing it.

 

Help would be appreciated. Let me know if any logs or whatever would be helpful.

I do not think that Unassigned Devices supports drives that are in ReFS format.

Google seems to indicate that the only linux driver available is proprietary so won't be supported by UD.

Hi,

 

I know the topic has been discussed many times here but I read all posts about this and cannot find anything useful to solve my problem.

 

On top of my array, I'm using 2 unassigned drives, one is a spare drive, unmounted, the other one is mounted and shared over the network (SMB).

Both drives are identical (Western Digital 8TB WD80EFZX).

 

Now my issue is that I would like so spin down both of these drives when they are not used.

The spare one is spinning down normally.

The second one (mounted and shared) does not spin down.

My questions are:

- is that the standard behaviour ?

- if I check the power management setting on the drive using

hdparm -I /dev/sdg |grep level

I get the following:

     Advanced power management level: 164

 

Where does this 164 value comes from  ? Unassigned devices is supposed to set this value to 180 (180 * 5s = 30 minutes)

 

I checked this value on the other drive (the spare drive), and it's configured the same to 164

 

- Last info, if I use

hdparm -y /dev/sdg

then the drive spins down properly and remains in sleep mode until I access it over SMB.

 

 

So I don't get why the hell the drive does not go to sleep on its own when unused ?

Can I change that ?

 

Thank you for your help

Does anyone know if there is a way to get disk io from the attached unassigned devices?  I'd really like to be able to visually see real time so I can guage the amount of writing to my attached SSD's.

 

Thanks.

The all are of the following type:

That's likely the best way, you can also keep -a and just add the --no-perms flag, e.g.: rsync -av --no-perms etc

  • Why do the permissions problems happen when trying to copy to /mnt/disks/Drive_Name?
  • I see it in Midnight Commander and rsync
  • I've formatted the external hard drive via the U.D. plugin to exFAT (I need macOS read/write compatibility) and I have these errors
  • I could simply attach the HDD to my computer and transfer through SMB, but it's slower in doing so. Plus, macOS's merge function in the Finder isn't straight forward
    • The same goes if I mount the HDD to the Unraid server via U.D. and then transfer the files from the macOS VM via SMB = slow
  • Seems to happen when the functions are trying to create the base folders on the external HDD at the drive's root level

Well, exFAT as far as I know doesn't support permissions.  My first guess (and some small memory of having done similar years ago) is this is part of why.  Though in that case the files did copy and the error was informational.  I can't tell with your rsync logs, but certainly MC doesn't seem to be informational.

 

rsync does have an option to skip permissions.  I think it's --no-owner --no-group and / or --no-permissions.  Or using archive (a) with rsync, maybe don't use that as that explicitly copies permissions.

 

I can confirm it doesn't happy on my UD drives, though all of those are either XFS or BTRFS.

 

Edit: If it really becomes a problem, you could just copy to the network share within unraid.   Internal unraid network copies are 10Gb so not too bad.  The share would get around the permissions problem I think.

Because exFAT doesn’t understand permissions, owners, or groups.

Everything hangs when a disk is spinning up - that's to be expected. A disk refusing to spin up doesn't sound like a UD problem. My HDD spins up fine when accessed.

sure but it hangs endless.... maybe its a Kodi nor a TVH Problem too. TVH runs under a debian VM in unraid

Whenever an smb mounted share goes offline, the server webgui refuses to load resulting in a 504 gateway timeout. Even when the server smb share returns to online status. This occurs on all 3 of my servers. 

 

Is this a timeout issue that can be fixed? It's quite annoying to have to reboot the server to regain access to the web gui.

 will do. I've currently got 2 servers giving the error making them unaccessible. but one is preclearing a 10tb disk. the other has ssh disabled... so I'll have to replicate the situation on the non-preclearing server tomorrow (after enabling ssh)

I think i might have something similar going on but I could never figure out what was making it happen.  A lot of mornings I am finding that I lose access to the Web GUI with a 504 error right before I do a backup.  I can still access with SSH and my files are still shared but I can't reboot or even post diagnostics.  I have to do a reboot with the power button and then it has to do a parity check which is not fun.   I have had it happen the past 2 nights but it has seemed to be going on for a month and has happened a couple of times.

this server wouldn't respond in CLI to diagnostics command but I was able to get the syslog to copy to the flash.... it's something I guess. you'll see that a few minutes after the network connection times out, nginx tanks. I'll try to get something off the other, but it has ssh disabled and with no webGUI, not sure what I can do (thought I do have access to the flash drive via share)

It is not directly a problem with the remote server or network, but rather, how UD handles remote mounted shares that go offline. It occurs across all 3 of my installs,  when a mounted smb share goes offline (not randomly, typically are offline when I'm doing an unRaid os update, or hardware swap).

 

 

its a reproducible error/problem caused only by interaction with UD, as demonstrated below, carried on just now on a fresh boot:

 

I have server A connected via smb to server B (both running unRaid)

I stopped the array on server B, imitating an os update/reboot.

Server A, still has the remote share mounted in UD from Server B on my local network

Server A tries  to find server B but can't

After timing out, the gui section for mounting remote shares disappears  (as indicated by the moving graphic which stops moving and shows only the disks inside the server.

At the same time, the nginx upstream timeout occurs in the logs (watching live updates via tail)

Jun 28 07:23:00 Twins nginx: 2019/06/28 07:23:00 [error] 5371#5371: *1961 upstream timed out (110: Connection timed out) while reading upstream, client: fe80::c48:f133:39ab:5f21, server: , request: "POST /plugins/unassigned.devices/UnassignedDevices.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "twins.local", referrer: "http://twins.local/Main"

 

 

There is no way to unmount missing share in the webgui now

it returns "resource busy" in CLI, additionally, forcing it off does not work either

Clicking on any tab other than main, the webgui is still functional for a short time and runs without error.

Returning Server B back online (that hosts the remote share) still results in web gui loading icon. when it times out, UD displays disks in that server as before, no remote shares or section where that option is normally preset is visible. 

 

after multiple refreshes of main tab, web gui can crash (and often does for me)

even when having the ability to shut down via web gui, UD hangs the shutdown

I believe the active pid is UD related at this point, considering the server otherwise shuts down normally when the remote share is constant.

 

 

 

Attempted retrieval of diagnostics from the web gui resulted in no zip download occurring. syslog is here minus the shutdown section shown above: syslognew.txt

 

 

I really appreciate your time and assistance on this

Has anyone been able to figure this out? I've tried a different NIC, a different cable, and moved the PCI slot the NICs are in on both servers and made no progress. Is there a way to monitor Samba or spit out some logs for it to see if that's maybe crashing and causing the issue?

Is there a reason why utilization of unassigned disks isn't shown on the dashboard page?

UD uses the 'df' command to get the mounted devices size information.  'df' has a nasty habit of hanging indefinitely if a device is off-line.  Because of all the issues with 'hangs' on remote mounted devices, I have set a timeout of 1 second on the 'df' command.  After 1 second, the 'df' command fails and the size is set to 0B.

 

It may be that the timeout is too short.  I have to balance the timeout to be long enough to get the information in normal operation vs. having UD appear to hang when the 'df' command is taking too long.

 

Post your diagnostics.

You need to post this as an feature request.  The UD plugin doesn't have any control over the dashboard page.

I believe the active pid is UD related at this point, considering the server otherwise shuts down normally when the remote share is constant.

 

 

 

Attempted retrieval of diagnostics from the web gui resulted in no zip download occurring. syslog is here minus the shutdown section shown above: syslognew.txt

 

 

I really appreciate your time and assistance on this

 

 

 

I have spent a lot of time on the UD plugin to keep it from appearing to 'hang'.  The issue comes from some commands UD uses to get the mounted devices information.  Remote mounted devices using CIFS mounts are particularly messy because of the 'df' command used to get remote mounted devices information and the way servers going off-line are handled.  I've set timeouts on all commands that I can to keep UD from hanging, but there may be more that needs to be done.  I can't reproduce the problem with the setup I have, so it is very difficult to fix the issues you are seeing because it is probably related to your particular setup.

 

You can't unmount a remote mounted share when it goes off-line because CIFS reports the mount as busy.  Unless UD does a forced unmount, the device won't unmount.  It is not a good idea for UD to do a forced unmount, because the device could actually be busy.

 

My suggestion is to unmount any remote mounted shares before you take the remote server off-line.

 

Also, any of you having any issues with UD, please remove the preclear plugin and reboot your server.  The preclear plugin is partially integrated with UD (that's why you can see preclear information in UD), and there is a background preclear task that collects device information that may have some issues.  I don't have the time or desire to troubleshoot preclear.  There has been a lot of discussion about the need to preclear disks.  It really isn't necessary and the preclearing has been a source of problems.  I know all you preclear fanatics will want to start a debate about it, but for troubleshooting these issues, please get it out of the way.

 

Post your diagnostics from normal operation.
