Hi btrfs-team/-users, I do observe a strange behavior upon booting of my openSUSE 12.1 system ( kernel 3.1.10-1.9-desktop; x86_64 ) with btrfsprogs-0.19-43.7.1.x86_64 utils installed: The system has two btrfs-vols: root(sda7) & home(sda8) and had been created during system setup of openSUSE 12.1: # btrfs filesystem show Label: none uuid: a288fcff-28c8-4764-8efe-1e0cb205d588 Total devices 1 FS bytes used 27.25GB devid 1 size 106.88GB used 67.29GB path /dev/sda8 Label: none uuid: 4b3e5746-31aa-405a-a41f-540376ea5110 Total devices 1 FS bytes used 17.93GB devid 1 size 40.00GB used 25.54GB path /dev/sda7 Btrfs v0.19+ The home-volume can not be mounted upon started with the msg: btrfs: Error removing orphan entry, stopping orphan cleanup btrfs: could not do orphan cleanup -22 Booting from the latest systemrescuecd (based upon Linux-kernel-3.0 :-( ) a btrfsck-run on the home-vol(sda8) does not report any errors! Whereas upon sda7 I got a lot of reportings concerning /tmp, /.snapshot, /var, /srv, /opt. But I''m sure these msgs are related to the openSUSE 12.1 way of setup including the snapper-feature, because there a lot of subvols: # btrfs subvolume list / ID 256 top level 5 path tmp ID 258 top level 5 path opt ID 259 top level 5 path srv ID 260 top level 5 path var/spool ID 261 top level 5 path var/log ID 262 top level 5 path var/run ID 263 top level 5 path var/tmp ID 271 top level 5 path .snapshots ID 278 top level 5 path .snapshots/5/snapshot ID 575 top level 5 path .snapshots/293/snapshot ... ... many, many more Further I recognize in /var/log/messages some btrfs - orphan related entries: Apr 17 09:06:57 ctrlaltdel kernel: [ 3120.205958] btrfs: unlinked 1 orphans Apr 17 09:10:04 ctrlaltdel kernel: [ 3307.607220] btrfs: unlinked 15 orphans Apr 17 09:11:04 ctrlaltdel kernel: [ 3367.233679] btrfs: unlinked 15 orphans Apr 17 09:11:44 ctrlaltdel kernel: [ 3407.023880] btrfs: unlinked 16 orphans Apr 17 09:11:51 ctrlaltdel kernel: [ 3414.172983] btrfs: unlinked 16 orphans .... .. . ....

Since now I do not get any hourly generated oprhans logs. But upon a system restart I need to ro-mount with a following rw-remout manually, again. Any suggestions what to do? Kind regards for your help.

Nevertheless, perhaps this info is still valuable to further improve btrfs. regards, henrik -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
