Re: CRC error prevents hammer reblock. What to do?
:I also got a kernel dump this night. I couldn't restore the dump until now
:because of some issues with dumpdev not being swap. But this might be
:related
:
:Unread portion of the kernel message buffer:
:panic: assertion: bcmp(&elm->leaf, &leaf, sizeof(leaf)) == 0 in
:hammer_reblock_helper
:Trace beginning at frame 0xd914f724
:panic(d914f748,d914f7f4,c3047bc0,d914f7b4,d914f8ac) at panic+0x8c
:panic(c0597763,c0603ed8,c0582e58,c3047b80,0) at panic+0x8c
:hammer_ioc_reblock(d914fa58,d33e16d0,c2b19540,d914f964,d914f8d8) at
:hammer_ioc_reblock+0x41f
How old is this kernel? This used to be an assertion but is now
a warning which causes the reblocker to retry the operation. It
occurs due to a race during a record deletion.
