Hello, Currently I try to realize a Filer Setup, based up on FreeBSD 9 with Carp, HAST and ZFS. Failover etc works fine so far, but when I start writing data on the ZFS device the following error pops up continuously: Dec 17 14:59:06 filer1 hastd[2211]: [disk7] (primary) Remote request failed (Operation not supported by device): FLUSH. Dec 17 14:59:06 filer1 hastd[2205]: [disk5] (primary) Remote request failed (Operation not supported by device): FLUSH. Dec 17 14:59:06 filer1 hastd[2202]: [disk4] (primary) Remote request failed (Operation not supported by device): FLUSH. Dec 17 14:59:06 filer1 hastd[2193]: [disk1] (primary) Remote request failed (Operation not supported by device): FLUSH. Dec 17 14:59:06 filer1 hastd[2220]: [disk10] (primary) Remote request failed (Operation not supported by device): FLUSH.

Dec 17 14:59:06 filer1 hastd[2196]: [disk2] (primary) Remote request failed (Operation not supported by device): FLUSH. I already found threads where setting vfs.zfs.vdev.bio_flush_disable=1 seemed to fix this, for me it had no effect. Also i tried setting metaflush off in hast.conf, which doesnt change anything, too Hardware Platform is a Dell Poweredge R515, with Perc H700 Controller (configured to 10 Raid-0 Devices to get the single Disks). Any Ideas how to fix this? Cheers, Juergen
