We're currently = trialling this controller, an HP LSI board = (https://h10057.www1.hp.com/ecomcat/hpcatalog/specs/provisioner/05/347786-= B21.htm), but we're finding that it has some issues with the mpt driver, = namely: Driver doesn't seem to realize when a drive has been pulled, instead = mptutil shows that the drive is still there but only 512B in size. Driver also doesn't seem to realize when a drive has been reinserted Both of those seem to end up leading to corruption in the zpool. Another weird thing with that card, is that if a drive is pulled and the = card reinitialized (for example rebooting), the order of the drives = shift (i.e. if you pull da2, da3 becomes da2, da4 becomes da3, etc), = which again causes problems with the zpool. Anyway, the LSI SAS 9211-8i looks like a nice card, but am having = difficulties determining if it'll be supported by the mpt driver. Does = anyone know if it'll work, or does anyone have any suggestions for a = good JBOD controller for ZFS and hotswap?
