SOLVED: Multiple drives cause partition conflict + pooling not working

[grimcabana]

It's two issues but I'm posting both in case they're related. Running f21/Amahi 8. Searched the forums for possible solutions, but didn't find any.

Partition conflict:
I have 4 drives I'm using for Amahi - a boot/root drive and 3 additional I want to use for Greyhole (1x2TB, 2x1TB). These were partitoned (automatically), formatted (ex4) and mounted in the dashboard.
If only one drive is selected for pooling, ghlog shows no errors. BUT selecting more than one drive generates

Code: Select all

CRITICAL daemon: ERROR: The following storage pool drives are on the same partition: /var/hda/files/drives/WD2TB/gh, /var/hda/files/drives/WD1TB/gh, /var/hda/files/drives/SAMSUNG1TB/gh. The Greyhole daemon will now stop.

I should note that in my first Amahi install (sort of a test run, I got a new router for this 2nd attempt) with the same hardware I didn't have this issue.
Selecting only one works fine, except for...

GH not pooling:
I tested uploading with a 1GB video file, which worked fine. The problem is that based on Dashboard's space free %, the file is on the root drive (/var/tmp), not on the drive I checkmarked to use for pooling.
"Videos" shares is marked for pooling; the location (LZ?) is /var/hda/files/videos.
Also, dashboard's Drive Pooling tab shows the root with a warning icon and link to a 'Greyhole not on root' page. The language is confusing - not sure if this is meant as cautionary advice or if it's telling me Greyhole is currently on the root and should be changed.

So the questions, put short:
- How can I resolve the partition error?
- How can I get GH pooling to the desired drive(s) instead of the root?

Thanks

Please provide the URL for the following command:

Code: Select all

fpaste --sysinfo

Also when you add files to the HDA, the go to the LZ first. Then when the Greyhole fsck is run, it will move the file accordingly. You can force that as well, but important your LZ is large enough to handle the files.

Also, dashboard's Drive Pooling tab shows the root with a warning icon and link to a 'Greyhole not on root' page. The language is confusing - not sure if this is meant as cautionary advice or if it's telling me Greyhole is currently on the root and should be changed.

That is telling you that it is discouraged adding that partition to the pool as it's the root drive and can fill up quick. You should not have that box selected for best results.

Thanks for the timely response

Can you also post the contents of /etc/fstab?

Few more questions:

A. Did you install Greyhole manually or use the Amahi Greyhole UI application?

B. How did you mount the drives, manually or using Amahi Disk Wizard?

C. Have you checked to see if you can access files or directories on the drives?

fstab:

Q&A:

A. Did you install Greyhole manually or use the Amahi Greyhole UI application?

I used Greyhole UI. Haven't changed the default share paths or anything else.

B. How did you mount the drives, manually or using Amahi Disk Wizard?

Mounted, formatted and partitioned with Disk Wizard

C. Have you checked to see if you can access files or directories on the drives?

Something odd here. When I was working on this last Friday, I could access the test video file via OS X Finder. But coming back to it after the weekend, the file isn't shown in OS X. HDA Dashboard still shows the drive space being used, and checking /var/hda/files/videos in ssh shows two copies of the file, I think. I'm a beginner, so tell me if I'm just reading this wrong:

Code: Select all

. ._ .. ._Louis_CK_Beacon_1280x720.mp4 Louis_CK_Beacon_1280x720.mp4 ._.VolumeIcon.icns .VolumeIcon.icns

[bigfoot65]

That is odd.

Linux does not play well with UPPER CASE names, but that should not be causing the issue.

Please provide the /etc/greyhole.conf file. Also does each drive have a folder labeled gh?

[grimcabana]

greyhole.conf:

Code: Select all

The drives do not have a gh folder, just 'lost+found'. Should I try creating 'gh' using the storage_pool_directory path?

Yes.

I also see only one drive listed in /etc/greyhole.conf. Once you get the folder created on the other drives, check to ensure they are enabled in the file. This may require a restart of Greyhole as well.

Created gh subdirectories in all drives and enabled them in dashboard Drive Pooling. Rebooted server, and all appear in greyhole.conf. The 'same partition' error is gone, but now ghlog tells me:

Code: Select all

WARN daemon: Warning! It seems the partition UUID of /var/hda/files/drives/WD2TB/gh changed. This probably means this mount is currently unmounted, or that you replaced this drive and didn't use 'greyhole --replace'. Because of that, Greyhole will NOT use this drive at this time.

Only for the one drive; there aren't any warnings for the other two.

[bigfoot65]

That is progress.

Recommend you execute the command as indicated and it should clear up your issues.
