Well, I've run every exercise tool I can think of and the hardware seems solid as a rock. The machine still crashes when I try to look at anything /usr/bin with a long listing or if I try to go to /usr/src and perform a "make buildworld". The errors all seem to point to ZFS. That is, the panics always occur during some type of ZFS operation. My consistent one (this is after going through each 2GB of the four I have swapping each) is this: zfs_fuid_map_id I can infer what it means but everything in the search engines refers to zfs_fuid.c as to where this issue lay and it was "fixed?". Again, I believe that ZFS is corrupted in some way and I need to roll things back or clean up a section of disk. I re-ran scrub on the pool. The mirror has disk 1 and disk 2. It resilvered disk2 for 563 GB and 99.6% of the time and 0m time remaining. However, after that time, disk 1 started creeping up to 370 MB from 250MB....I was waiting for it to complete when it panic'd. Thank you, Paul ________________________________ From: Bob Friesenhahn To: Paul Pathiakis Cc: freebsd-fs@freebsd.org Sent: Tue, January 26, 2010 1:34:51 PM Subject: Re: ZFS - scrub lead to corruption?

However, why did the scrub cause it to crash? Zfs scrub is often the most intense thing you will do with your computer. It tends to uncover problems which are not necessarily related to zfs. If you are not using ECC memory, then bad memory is the first thing you should check for. > Please let me know. (Bob, BTW, I just checked into OpenSolaris bootable CD it's nice, you may want to check it out - FreeBSD is still a passion due to it's BSD storied history.) OpenSolaris has not been quite to the state where I feel that I should use it. Perhaps in three months (next OpenSolaris release) the situation will have changed. Meanwhile my FreeBSD system has been solid as a rock since 2003.
