Were there log errors in /var/adm/messages or did you need to check the controller loogs with something like lsi util?
Did the reset workaround in the blog post help? The expanders you were using were SAS/SATA expanders? Or SAS expanders with adapters on the drive to allow the use of SATA disks? I've been using 4 X-25E's with Promise J610sD SAS shelves and the AAMUX adapters and have yet to have a problem. > Our solution was to move the SSD's off of the expander and remount > internally attached via one of the LSI SAS ports directly (we also had > problems with running the drives directly off the on-board SATA ports > on our SuperMicro motherboards -- occasionally the entire zpool would > freeze up). I'm surprised you had problems with the internal SATA ports as well- any idea what was causing the problems there? -Don _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
