Hi ! It is strange because I've checked the SMART data of the 4 disks, and everything seems really OK ! (on another hardware/controller, because I needed Windows to check it). Maybe it's a problem with the SAS/SATA controller ?! One question : if I halt the server, and change the order of the disks on the SATA array, will RAIDZ still detect the array fine ???? The idea is to check if the results (big service times) depends on the drives position, or on the hard drives themself ! Thank you ! -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
