..oh and fstab: Code: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

I had to change the hostname after my installation from cw-ts to cw-ws because of a typo. Could this be causing any of the problems? Any insight is greatly appreciated.
I'm guessing there is some bug with quota and new kernels, I get similar syslog errors on a Fedora 12/ispconfig3 setup. Since I don't need quota in my environment I just turned quota off by changing fstab. I'm using 2.6.31 kernel btw. Your fstab mount point sounds like you're mounting on a lvm volume.
Hmm, my knowledge with kernels is extremely little. About all I know is the Code: uname -r code. I've disabled quota just for the sake of disk space. Is there anything that you recommend to troubleshoot the problem? I don't even know where to begin. I've heard of compiling your own kernels, but wouldn't have the slightest clue how if that were to help my problem.
Okay, I'm not sure what fixed it but I just updated to linux-image-2.6.31-20-generic-pae via apt-get update/upgrade and also changed my /etc/fstab to remove an extra 0 that I found after the options. Re-enabled Quota and everything seems to be fine ::fingers crossed::
Quota problems Hi, I'm also using the 2.6.31-20-generic-pae kernel. wich 0 needs to be removed from my fstab below? UUID=235160e2-d150-4e75-996c-68207a4c40f6 / ext4 errors=remount-ro,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 0 1 Thanx, Tim
@t.roijers, your /etc/fstab looks fine to me. I'm still battling this problem. I just used apt-get and there was a new kernel update, so I turned quota back on. Besides obviously checking for these same sort of errors in the error log, is there a way to check if quota is actually working?
I had a Debian Squeeze box with ext4/quotas up for 200 days, then went down last week. The syslog was filled with the exact error at the beginning of the thread. Perhaps a kernel issue? I believe I had 2.6.32-4 or similar. Lewis
