As I posted about a while ago I had memory corruption, after fixing the problem I ran a scrub that found a few errors that I fixed. I then started zdb -cvv to check the metadata. Thats 8 days ago. It didn't print out anything, just consumed 600MB of memory and 5% of the cpu. This morning I saw that it had crashed: # zdb -cvv media Traversing all blocks to verify checksums and verify nothing leaked ... zdb_blkptr_cb: Got error 86 reading <441, 8198, 0, 1ff51> -- skipping zdb_blkptr_cb: Got error 86 reading <447, 0, 1, 0> -- skipping error: zfs: freeing free segment (offset=4372277157888 size=8192) [1] 16661 abort zdb -cvv media And in the log file I saw: pid 16661 (zdb), uid 0: exited on signal 6 I take it something is wrong, but what? And how do I fix it? The file system seems to be working great. -- Ståle Kristoffersen staalebk@ifi.uio.no
