Hi, Not sure if this is supposed to be like this or if I have set it up wrong. I have a vinum mirror with the total size supposed to be 1024M. But, here is what df -h reports: /dev/vinum/mirror 1.9G 1.0K 1.8G 0% /usr/local/var/nntpcache-map which makes it appear as if the disks are striping. However, vinum reports the following under list: S mirror.p0.s0 State: up PO: 0 B Size: 1023 MB S mirror.p0.s1 State: up PO: 1023 MB Size: 1023 MB Im confused. Is this a bug or have I set something up wrong? I thought mirroring a drive would allow you to have a partition on one disk drive, and when its written it writes to both drives at the same time. Below is my Vinum configuration (Ignore the vinum0 volume, that is setup and works fine :) ) # Vinum configuration, saved at Thu Jul 19 10:34:27 2001 - Jamie drive vinumdrive0 device /dev/da1e drive vinumdrive1 device /dev/da2e drive vinumdrive2 device /dev/da3e volume vinum0 plex name vinum0.p0 org striped 512s vol vinum0 sd name vinum0.p0.s0 drive vinumdrive0 plex vinum0.p0 len 69584384s driveoffset 265s plexoffset 0s sd name vinum0.p0.s1 drive vinumdrive1 plex vinum0.p0 len 69584384s driveoffset 265s plexoffset 512s sd name vinum0.p0.s2 drive vinumdrive2 plex vinum0.p0 len 69584384s driveoffset 265s plexoffset 1024s # Mirror drive vinumdrive3 device /dev/da3a drive vinumdrive4 device /dev/da2a volume mirror setupstate plex name mirror.p0 org concat sd name mirror.p0.s0 drive vinumdrive3 size 0b sd name mirror.p0.s1 drive vinumdrive4 size 0b Please let me know if I have miss-configured something. Cross posted to stable incase it is a bug, more than likely i've got something wrong somewhere though so apologies in advance ;) Thanks, -- ======================================================== Jamie Heckford | jamie@uk.clara.net Systems Administrator | 020 7903 3015 Clara.Net | www.clara.net ======================================================== To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
