Hi, I got the following panic when rebooting after a crash on 7.2-REL: panic: solaris assert: dmu_read(os, smo->smo_object, offset, size, entry_map) == 0 (0x5 == 0x0), file: /usr/src/sys/modules/zfs/../../contrib/opensolaris/uts/common/fs/zfs/spa ce_map.c, line: 341 This seems to be the same panic as mentioned here: <http://lists.freebsd.org/pipermail/freebsd-stable/2008-July/043763.html>. However, I did not see warnings about the ZIL. The crash leading to this situation was probably caused by me pushing the controller card a bit too hard (mechanically) during operation (well, so much about hot-plugging of cards :-). Since my pool was almost empty anyway and I needed the machine, I opted to recreate the pool instead of trying the patches supplied by pjd@ in the thread above. But nevertheless I would like to be prepared if this happens again (and the pool is not empty :-). Right now I am updating the system to 8.0-RC2. Will this issue go away with zpoolv13/FBSD8.0 (as suggested above)? I could not find out from the thread above if the suggested patches helped or if anything from this has been commited at all. Pawel or Daniel, do you remember what the final result was? cu Gerrit
