Things seem to have stabilized recently as the last occurrence I witnessed was on May 13th.
I searched all my 2014 and 2015 logs for "ext4_mb_generate_buddy" and here is what I got: Nov 24 02:54:03 smb kernel: [842091.081319] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 1, block bitmap and bg descriptor inconsistent: 8198 vs 8197 free clusters Jan 18 06:25:17 ns0 kernel: [330912.633362] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 3, block bitmap and bg descriptor inconsistent: 17617 vs 17616 free clusters Jan 19 06:30:38 ns0 kernel: [417633.256202] EXT4-fs (vda1): initial error at time 1421580317: ext4_mb_generate_buddy:756 Mar 1 06:25:08 ns0 kernel: [154713.220446] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 4, block bitmap and bg descriptor inconsistent: 17270 vs 17268 free clusters Mar 2 06:26:44 ns0 kernel: [241210.340779] EXT4-fs (vda1): initial error at time 1425209107: ext4_mb_generate_buddy:756 Mar 4 06:25:09 pm kernel: [75552.905227] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 6, block bitmap and bg descriptor inconsistent: 9361 vs 9359 free clusters Mar 15 06:25:12 smb kernel: [231369.706448] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 3, block bitmap and bg descriptor inconsistent: 17537 vs 17536 free clusters Mar 23 16:24:25 apt kernel: [ 38.398673] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 33, block bitmap and bg descriptor inconsistent: 22354 vs 22352 free clusters Mar 26 06:25:18 pm kernel: [223295.593946] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 6, block bitmap and bg descriptor inconsistent: 11499 vs 11497 free clusters Apr 13 17:42:38 smb kernel: [422214.146392] EXT4-fs error (device dm-4): ext4_mb_generate_buddy:756: group 256, block bitmap and bg descriptor inconsistent: 672 vs 671 free clusters Apr 14 09:31:22 smtp kernel: [479136.955401] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 1, block bitmap and bg descriptor inconsistent: 7688 vs 7686 free clusters Apr 26 06:25:07 ns0 kernel: [767851.910454] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 0, block bitmap and bg descriptor inconsistent: 22322 vs 22321 free clusters Apr 27 06:27:00 ns0 kernel: [854365.159204] EXT4-fs (vda1): initial error at time 1430043907: ext4_mb_generate_buddy:756 Apr 27 06:27:00 ns0 kernel: [854365.169903] EXT4-fs (vda1): last error at time 1430043907: ext4_mb_generate_buddy:756 May 7 08:37:08 log kernel: [ 33.482706] EXT4-fs error (device vdc): ext4_mb_generate_buddy:756: group 2, block bitmap and bg descriptor inconsistent: 28613 vs 28611 free clusters May 8 08:39:00 log kernel: [86545.376048] EXT4-fs (vdc): initial error at time 1431002228: ext4_mb_generate_buddy:756 May 8 08:39:00 log kernel: [86545.376051] EXT4-fs (vdc): last error at time 1431002228: ext4_mb_generate_buddy:756 May 13 06:25:13 git kernel: [131633.710249] EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 5, block bitmap and bg descriptor inconsistent: 14076 vs 14074 free clusters -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1423672 Title: ext4 turned read-only during logrotate daily run To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1423672/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
