Hi List, A few days we exported a zpool which caused our system to panic. Ever since we are able to reimport the pool. We are quite sure all data is intact sinse the pool is located on raid 10 and the other pools still work. We copied the entire disk (iscsi) to a file and placed it back on a ide disk to make sure the problem wasn't system/iscsi related.
We've tried many solaris releases as well as build 61 with the /etc/system entry. Nothing worked. Then we tried zfs on linux with fuse. This also resulted in the same error. We avoided the problem by modifying the checksum function from zio_checksum.c by putting return 0; as the first line. So the bug is there somewhere. The zpool is now imported and we can access our data. This is our problem (we have crashdumps.... quite a lot ....) log crash entry: Apr 6 15:50:50 rbgz02 genunix: [ID 809409 kern.notice] ZFS: bad checksum (read on <unknown> off 0: zio ffffffff9bc7fa00 [L0 packed nvlis t] 4000L/400P DVA[0]=<0:1480013c00:400> DVA[1]=<0:b00053000:400> fletcher4 lzjb LE contiguous birth=1791755 fill=1 cksum=6730853727:29b04 d00d6a8:b64ae1f6b3080:27fe414eb9930b6): error 50 Apr 6 15:50:51 rbgz02 unix: [ID 100000 kern.notice] Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010baac0 zfs:zfsctl_ops_root+2fe39f02 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010baad0 zfs:zio_next_stage+72 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bab00 zfs:zio_wait_for_children+49 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bab10 zfs:zio_wait_children_done+15 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bab20 zfs:zio_next_stage+72 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bab60 zfs:zio_vdev_io_assess+82 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bab70 zfs:zio_next_stage+72 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010babd0 zfs:vdev_mirror_io_done+c1 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010babe0 zfs:zio_vdev_io_done+14 () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bac60 genunix:taskq_thread+bc () Apr 6 15:50:51 rbgz02 genunix: [ID 655072 kern.notice] fffffe80010bac70 unix:thread_start+8 () We can provide more details if required...
