It's unfortunate gvinum was never able to recover from the GEOM-age, until now maybe. :-) However, do you think that it's performance is affected too? Last time i tested, i was not impressed with gvinum's RAID5 performance, write speeds were very low. RAID0 and RAID1 appeared to be on par with gstripe and gmirror though. I guess gvinum is primary for people who feel comfortable with its configuration and user-interface. > Therefore, I hope many will > test this patch and help discovering bugs that otherwise would just stay there. > I will be able to test this on my new test system, coming Wedsnesday. This consists of a modern dualcore AMD 3GHz processor with 4GB RAM and 8 SATA disks. If you like, i can report my findings to the list when i'm done. Regards, Veronica
