got up this morning to find my server root filesystem (btrfs) full.

found to snapshots taking up ~40GiB, removed (snapper delete ###) cleaned up some archived log files, rsyslog

currently: # btrfs filesystem df / Data, single: total=74.10GiB, used=72.87GiB System, DUP: total=32.00MiB, used=16.00KiB Metadata, DUP: total=1.00GiB, used=492.22MiB GlobalReserve, single: total=116.84MiB, used=0.00B

filelight shows 45.9GiB total usage

why does my btrfs system still show 73.83Gib used?

Richard, are you here?

why does my btrfs system still show 73.83Gib used?

Richard, are you here?

I am not Richard but start with showing

btrfs sub list -qu / btrfs qgroup show /

What "btrfs sub get-default /" says? Also current mount table (/proc/self/mountinfo)?

btrfs sub get-default / ID 5 (FS_TREE)

cat /proc/self/mountinfo ... 62 0 0:37 / / rw,relatime shared:1 - btrfs /dev/sdc3 rw,space_cache,subvolid=5,subvol=/ ...

OK, so you have older layout (I almost forgot how it looked like). It makes it less convenient. Could you show

btrfs fi du -s /.snapshots/*/snapshot umount /.snapshots btrfs fi du -s / mount /.snapshots

I disabled and removed all the snapshots to get enough room to continue to operate :^(

btrfs sub list -qu / ERROR: can't perform the search - No such file or directory

So 42.2 did not yet enable quota by default.

how do I set "quota" to prevent this in the future?

Quota on btrfs has its own can of worms and it is not enough to simply enable it, snapper needs to know how to make use of it. It probably still did not use quota on btrfs in Leap 42 anyway. Quota can be used manually to get better estimation of where space goes, let's wait for du result.

I appreciate your help and efforts, but I may have found the problem. the system has an external 4T ext4 usb drive that was showing nearly full with only 80G of data. I transfered the data to a b/u drive and reformatted the drive, replaced the data and now my server system shows: btrfs filesystem us / Overall: Device size: 80.00GiB Device allocated: 71.06GiB Device unallocated: 8.93GiB Device missing: 0.00B Used: 17.73GiB Free (estimated): 60.73GiB (min: 56.26GiB) Data ratio: 1.00 Metadata ratio: 2.00 Global reserve: 48.97MiB (used: 0.00B) Data,single: Size:69.00GiB, Used:17.20GiB /dev/sdc3 69.00GiB Metadata,DUP: Size:1.00GiB, Used:269.17MiB /dev/sdc3 2.00GiB System,DUP: Size:32.00MiB, Used:16.00KiB /dev/sdc3 64.00MiB Unallocated: /dev/sdc3 8.93GiB wtf....

I do not understand how another ext4 filesystem has anything to do with space consumption on btrfs filesystem. But if you say the problem is solved, good.

do you want/need any more information?

At this point when error condition is gone no usable information can be collected. I suspect you simply had large deleted files and process keeping them open was terminated.

I did have an external drive expire but the mount remains. maybe that had some effect. it is a server and I will not reboot unless forced. tks again -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
