How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies? The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that

Hi, once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones. Thanks, budy -- This message posted from opensolaris.org

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

I''m not sure if this is a problem with the iscsitarget or zfs. I''d greatly appreciate it if it gets moved to the proper list. Well I''m just about out of ideas on what might be wrong.. Quick history: I installed OS 2008.05 when it was SNV_86 to try out ZFS with VMWare. Found out that multilun''s were being treated as multipaths so waited till SNV_94 came out to
