Hello all, I findout the problem. It's due in part in my configuration but I think it an architecture some will use in near future: - I've got lots of iscsi disks which I import on solaris server - this pool is shared in zvol (and as iscsi target for other servers but it's a minor point here)
The problem is that devfsadm (that check all the devices during each call) takes long time to do it with iscsi drives. So when you do zfs import/volinit, it calls devfsadm to add the zvol newly found, but also recheck all the disks involved in the system (not necessary in the zfs tank we touch). Then with the latency for each iscsi device, it takes aroud 12 seconds for 10 zvol and 8 iscsi drives. If you doubles the number of iscsi drives attached, the time taken doubles. If you doubles the number of zvol created, the time taken doubles. Do you know if there's a way for devfsadm to configure staticly the iscsi devices so devfsadm take less time ? or do we need to change the source code of devfsadm or zfs ?
