Backups Disappearing?

Sure, I'll post it when I get home.

The results of the mount command:

[root@AMAHI ~]# mount
/dev/sda3 on / type ext3 (rw)

I found the problem.
Big files ( bigger than 2GB), on 32-bit systems.
I'm running on 64-bit, so I've never had a problem.
I'll see what can be done to fix this.

Thanks for the patience.

Great! That kind of makes sense with my test of small file sizes surviving.

I will set up trueimage to write files less than 2G until it's worked out.

Thanks for your hard work.

Code: Select all

rpm -Uvh http://greyhole.pommepause.com/releases/hda-greyhole-0.6.15-1.i386.rpm

This should fix your problem.
Once installed, try to create a file bigger than 4GB on your Greyhole shares, and see if it's still there the next day, and verify that /var/log/greyhole.log is not stuck in an infinite loop (trying to process task ID 0), like it was before.

That was quick...I will set it up in a few minutes, then run a backup. It only takes 30 minutes or so to image. Then I can fsck and see if it stays.

Hi, I had some trouble with trueimage last night, so nothing got backed up. I wonder if anyone has a better idea for an image backup that will do incrementals nightly like WHS, cause trueimage kind of bites.

Anyway, I did it when I got home this evening, broken down into 4.7 GB files. Then I did greyhole --fsck. Backup deleted, so no dice. Didn't survive.

Bad news.

Code: Select all

rpm -q hda-greyhole | fpaste tail -1000 /var/log/greyhole.log | fpaste

Please execute those commands and give me the URLs you receive.
You should execute the tail command before 4am, the day you did a backup that disappeared. Logs are rotated at 4am, so at that point, greyhole.log won't contain anything relevant anymore.

Here you go.

Ah! I think I found the problem.

It seems another function (fileinode) didn't work on 32-bit with big files, but I didn't see it earlier because the error message it throws is not shown in the greyhole.log! Plus, it's only used during fsck, thus why the file disappeared from the share at that point.

Code: Select all

rpm -Uvh http://greyhole.pommepause.com/releases/hda-greyhole-0.6.16-1.i386.rpm

This latest version should work better!
Try just a fsck, with that new version installed. Maybe the files that were removed will come back from the dead!
If not, try another backup, followed by fsck.
