Josef, this looks like it's running a bleeding edge 3.4-git kernel. Maybe worth looking at now This is probably that use after free bug. Can you try this patch and make sure it fixes the problem? http://www.spinics.net/lists/linux-btrfs/msg15862.html That patch is in current rawhide kernels. Any of the rc2 kernels should be good Mounted btrfs file system and it continued a perviously aborted (due to an oops) balance operation Package: kernel OS Release: Fedora release 17 (Beefy Miracle) Afraid I managed to get it to happen again with 3.4.0-0.rc2.git3.1.fc18.i686 kernel BUG at fs/btrfs/volumes.c:2518! invalid opcode: 0000 [#1] SMP Modules linked in: be2iscsi iscsi_boot_sysfs bnx2i cnic uio cxgb4i cxgb4 cxgb3i libcxgbi cxgb3 mdio 8021q garp stp llc ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ip6t_REJECT nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter w83627hf hwmon_vid ip6_tables nouveau ppdev ttm snd_via82xx_modem parport_pc snd_via82xx parport drm_kms_helper snd_seq gameport snd_ac97_codec ac97_bus drm snd_pcm mxm_wmi snd_mpu401_uart video snd_rawmidi snd_timer wmi snd_seq_device i2c_viapro snd i2c_core soundcore snd_page_alloc skge k8temp microcode btrfs zlib_deflate libcrc32c ata_generic pata_acpi sata_promise sata_via pata_via [last unloaded: scsi_wait_scan] Pid: 1192, comm: btrfs-balance Not tainted 3.4.0-0.rc2.git3.1.fc18.i686 #1 To Be Filled By O.E.M.

Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19 over a year with no progress.. Matt, is this still reproducible for you ? The system that reported the issues and its test btrfs volumes were decommissioned some time ago so I can't try the same volume but with an up to date kernel to try and reproduce. Given how much has changed since this bug was raised and the fact I haven't seen issues like this on other systems using newer kernels I'm happy for this to be closed. |
