vbox seems to have limit on boot disks - it appears to “see” 5, My vbox has IDE for boot disk, and I did add 6 sas disks, I only can see 5 — ide + 4 sas. So all you need to do is to add disk for boot pool, and make sure it is first one - once kernel is up, it can see all the disks. rgds, toomas > I'm not able to understand First 5 disks are ONLINE and remaining disks are > UNKNOWN state after power off and then power on > actually our requirement is to create RAIDZ1/RAIDZ2 with single vdev(upto 5 > disks per vdev) if more than 5 or less than 10 disks then those disks(after > 5disks) are spare part shouldn't be included any vdev. if we have > multiple's of 5 disks then we need to create multiple vdev in a pool > example: RAIDZ2 : if total 7 disks then 5 disks as single vdev, remaining 2 > disks as spare parts nothing to do. and if we have 12 disks intotal then 2 > vdevs (5 disks per vdev) so total 10 disks in 2 vdevs remaining 2disks as > spare. > RAIDZ1: if we have only 3 disks then we should create RAIDZ1 > > Here, we wrote a zfs script for our requirements(but currently testing with > manual commands).
