Greyhole on Amahi 7

[Strangename]

@Bigfoot - running that script you mentioned corrected the error - all up and running - 8.2 TB pool full fsck took around 70mins - much quicker than before so am judging it a success

[kikkegek]

cool!

that is good news

[bigfoot65]

Awesome! That can be something easily added to the install script I would think. Will have to ask cpg.

We can modify the app I built to do it.

good news over here too so far:

but the greyhole service is sleeping and telling me it has nothing to do? so what do I do next?

[jochen@localhost ~]$ greyhole -S

The following is the number of pending operations that the Greyhole daemon still needs to parse.
Until it does, the nature of those operations is unknown.
Spooled operations that have been parsed will be listed above and disappear from the count below.

I think its a folder permissions problem

[jochen@localhost drives]$ ls -al
total 20
drwxr-xr-x 5 root root 4096 Aug 11 21:44 .
drwxr-xr-x. 12 root root 4096 Aug 11 21:42 ..
drwxr-xr-x 4 root root 4096 Sep 11 2011 drive1
drwxr-xr-x. 16 root root 4096 Aug 5 12:41 drive2

drive2 has different permissions from drive1

could that be the problem?

I can see the shares.
I can also acces from my laptop (Windows7)
but there are no files there

drive1

[jochen@localhost drive1]$ ls -al

I have changed something in the proces to clean things up a little.

drive 2 was in the old /etc/fstab as:

UUID=485db5c1-4dce-4b5d-b270-60b05a87659d /var/hda/files ext4 defaults 1 2

and now it is in the /etc/fstab as:

UUID=485db5c1-4dce-4b5d-b270-60b05a87659d /var/hda/files/drives/drive2 ext4 defaults 1 2

[Strangename]

What I have is to run a fsck as soon as you reconnect all of your drives. Once that is finished I then do a fsck on just my individual directories.

e.g

Code: Select all

$ greyhole -f --dir=/var/hda/files/music

That way I find immediately any files somehow missed the first time around and secondly things like permissons tend to emerge. If you are still missing files rerun using the -o switch instead of the -f and that should pickup any files without metadata and recreate symlinks.

Probably not the most gracious way of doing things but it works for me.

[bigfoot65]

Yes permissions can be an issue. I typically set all folders in the /var/hda/files to my first admin user:users recursively.

[kikkegek]

okay guys,

late last night 0:05h I was able to get greyholestoragepool up and running on both drives and files are accesible.

I have found why it didnt the way I tried.

In the old setup the two drives (partitions) were mounted like this

#first disk including OS
UUID=485db5c1-4dce-4b5d-b270-60b05a87659d /var/hda/files ext4 defaults 1 2

#second disk added later, just one storage partition on this drive
UUID=667bd417-70f4-4524-ab03-501113edf499 /var/hda/files/drives/drive1 ext4 defaults 1 2

I added the second drive to my old setup, not thinking, and just going by whay the wiki told me:
https://wiki.amahi.org/index.php/Adding ... o_your_HDA

notice how for some reason the second harddrive got mounted "inside the storage partition" of the first drive that also holds the OS.

I wanted to clean up things, so I added a seperate drive (a 40GB SSD I bought) to hold only the OS and wanted to mount the two storage drives (partitions) like this:

#first disk including OS
UUID=485db5c1-4dce-4b5d-b270-60b05a87659d /var/hda/files/drives/drive2 ext4 defaults 1 2

#second disk added later, just one storage partition on this drive
UUID=667bd417-70f4-4524-ab03-501113edf499 /var/hda/files/drives/drive1 ext4 defaults 1 2

since this doesnt match the "old setup" greyhole recognized the two drives, but went to sleep, doing nothing and didnt show any files in my samba shares. funny thing is I didnt see any errors either.

that where I thought "well, might as well just try to mount it, like it was". Because that is what is told in this wiki:
https://wiki.amahi.org/index.php/Reconn ... orage_pool

files are back online now,so I am a happy camper.

But I would really like to clean my setup up.

What should be done to put the files and shares at my desired mount points like I described?

----------------------------------------------

a note to the AMAHI team:
if you use hda-diskmount on AMAHI7 for a second drive, do you then also run the risk of mounting it at the same point as I did? in another previous mounted share?

[bigfoot65]

By design, the drives mount in the drives folder located in /var/hda/files. Since you made your first drive mount in that location that is why it's in the storage pool.

You can mount drives pretty much anywhere you want. The only requirement is that the mount point exist, i.e. folder before you mount. So if you want to mount your drives as /var/hda/files/drives/drive1 and drive2 then the folders must exist there and have the correct permissions.

By default, the hda-diskmount script on ALL Amahi versions mount drives in those locations. You can manually change it of course, but must unmount the drives the remount in the desired locations as you indicate in /etc/fstab.

The wiki has a lot of good guidance, but it does not tell you to mount as /var/hda/files. It states you can and describes how, so it's your decision where you mount the drives. Having it mounted in the storage pool is not a big deal in my opinion, but I am no expert. If doing so causes a problem, then I would like to know the reason.

If you don't want drives mounted in /var/hda/files/drives location, then I suggest you pick a different location. Just remember that the Greyhole LZ needs to be in a location with sufficient space. I myself have a 200GB partition assigned as /var/hda/files and that serves as my LZ as well. In my case, it's sufficient. May not be for yours.

I got some errors on the WORKGROUP in the /var/log/messages

so I checked the smb.conf file and found that all my settings were removed again.

# This file is automatically generated for WORKGROUP setup.
# Any manual changes MAY BE OVERWRITTEN
# Amahi configuration, generated on 2013-08-12 11:24:33 +0200

what routine overwrites this smb.conf file? so where should I make my changes?
