Hello everyone, I had set up a raidz2 ZFS on ROOT system with 4 SATA disks. Every disk had 64k freebsd-boot, 30G freebsd-zfs and freebsd-ufs for the rest space. I did it with the gpart utility. One of the disks failed and I offlined the faulty 30G partition from the pool. The system worked with "no known data errors". After reboot I saw this message: "ZFS: zfs_alloc()/zfs_free() mismatch" and the system goes no further. I booted with FreeBSD 9.0-RELEASE usb stick, imported the pool which did scrub by himself somehow. After the scrubbing finished all seemed ok, but after reboot I see the message again. The system was FreeBSD 8.2-STABLE AMD64 with 4GB RAM. Interesting to note is that this is my second issue with a faulted disk. However if I replace healthy HDD for upgrading purposes, everything passes fluently. I pulled the data from /usr/home/ however part of it was damaged. I also posted about the issue here: http://forums.freebsd.org/showthread.php?t=31215 What can I do to prevent such a malfunction in future? Best Regards! Zlatko Asenov
