Amahi Forums

I am fairly new to Amahi and Greyhole, so please forgive me if I don't explain my problem very well. I will start by explaining how I have my HDA set up, and then I'll tell you what the problem is.

My HDA is an old laptop (Pentium M 1.7 Ghz, 100 Gb HD), I have a 2TB External USB 2.0 drive (formated as ext3) attached to it, that I would like to use to store my files on. Eventually, I would like to add a second 2 TB USB External hard drive which is currently connected to my Windows 7 desktop to the pool, but I need to get the first one up and running so I can migrate my files off of my machines and onto the server before I can add it to the pool.

My problem is that after following the instructions for adding another hard drive, I see my disk (under storage), but don't see the partition.

My software versions:
2.6.31.5-127.fc12.i686.PAE
samba-3.4.2-47.fc12.i686
hda-greyhole-0.7.5-1.i386

Your /dev/sdb1 partition isn't mounted.
("mount" doesn't show it)

If you added a new line in fstab, you should use the "mount -a" command to try to mount it.
If it doesn't work, an error should appear.

If it returns without errors, but you still don't see sdb1 in the result of "mount", then you probably didn't add what you needed to add in /etc/fstab.

You can "fpaste /etc/fstab" and paste here, and we should be able to point out your problem.

Thanks for the quick response.

"mount -a" gives me an error:

[root@home-server ~]# mount -a
mount: mount point /var/hda/files/drives/sdb1 does not exist
mount: mount point defaults does not exist

Ok, this is wierd, but I just checked the HDA, and the disk is now mounted. Question, I don't want my files to be stored on the 100Gb internal laptop disk, I don't have that disk selected as being part of the pool, is there anyway to prevent my files from being stored on that drive?

If it's not selected, it will only be used as a temporary placeholder for new files.
If you don't want that, you'll need to edit your shares Location (path) to point to something else than /var/hda/files/share_name
For example, you could change that to /var/hda/files/drives/drives1/share_name.

BTW, the error you now get when doing "mount -a" will probably prevent your computer from booting, the next time you reboot!
You should fix them ASAP.
The 'defaults' error is probably because you split a line you shouldn't have (defaults is on the beginning of a line, but it should be at the end of the previous line.)
And the sdb1 error might be an old drive you had mounted there. Is your new drive mounted in drives/sdb1, or in drives/drive1 ?
If it's in drives/drive1 (it should be; the new hda-diskmount script uses drive# folders, not sdX# anymore), then you can delete the line that reference drives/sdb1.

If you still have errors when doing "mount -a", just do "fpaste /etc/fstab" and we should be able to point out the problems.

Thanks to your help, I was able to fix the fstab, so I no longer get any errors when I "mount -a". My USB drive is now mounted on /var/hda/files/drives/drive1.

Thanks again.

I finally got all my data migrated onto the greyhole shares. I was in the process of formatting my second USB drive to ext3 format, when gparted crashed. This has led to one frustrating series of re-formats from NTFS then try to reformat to ext3. Somewhere in the process, I messed up my HDA install, as the machine would not boot. I have reinstalled my HDA, what do I need to do so I can add my first External drive into the pool without having to reformat and re-copy all my data to the pool?

Just follow the same instructions you followed to add the drive the first time.
But don't format it this time!!
Once it's included in the pool, launch a "greyhole --fsck" from a Terminal, and that should re-create the symlinks for all the files found in the drive you re-added in the pool.

If I added new shares, do I need to recreate those shares in the pool before I run the "greyhole --fsck"? Or wil running "greyhole --fsck" add all the shares for me?

You should never touch anything inside the gh folder.
Greyhole will create directories there as needed.
