I am using 4.11 and have been a FBSD user since the beginning of version 4. I successfully used vinum to create concatenated volumes that have grown over time. Vinum has proved very stable as long as the drives were IDE or SCSI. However I outgrew the confines of my case and added a firewire enclosure that contains two IDE drives. This was somewhere around 4.6. Initially, the firewire drives worked well once I learned I needed to set the SCSI delay kernel config option back up to 15 secs from 5 (unfortunately I lost my volumes getting that education). But when I upgraded from 4.9 to 4.10, vinum and the firewire devices didn't play well. I posted about it here: http://lists.freebsd.org/pipermail/freebsd-questions/2004-December/069290.html Later, I discovered there was an spb timeout issue that might be part of the problem and I posted about it here: http://lists.freebsd.org/pipermail/freebsd-firewire/2005-February/000331.html Anyway, I've been using the delete/create vinum volume workaround after every reboot as I never found a solution. But this last time, I lost both vinum volumes performing that workaround. I don't know what happened exactly other than fsck started getting disk errors. At the first problem, I answered 'n' and aborted the fsck. I tried the delete/create workaround again but was unable to stop or rm the subdisks, plexes, drives, etc. Then I rebooted. did the delete/create thing, but no longer could fsck read the disks. Without going on and on, the bottom line is that now I've lost both vinum volumes again. Since the bulk of my system is gone (I sure hope the tapes I have are good), I've decided to consider moving up to version 5. I've googled for info on gvinum but see a lot of posts about it being "flaky". What's it's status at this time? I really like having one large concatenated drive for storing my digital pictures, video, etc. but at this point, stability is more important. Also, how does ccd work with 5? I'd appreciate hearing of your experiences with vinum, gvinum, and ccd, especially as they relate to firewire devices.
