Can someone explain this to me ? I was testing gmirror/gstripe and
decided to
remove the vnode files stripe0 & stripe1. This resulted in a mirror
which kept on
working.....
 
 
/dev/mirror/mirro0 on /mnt (ufs, local)
 
DEVEL# ls /mnt/
.snap   anders  test    testje

DEVEL# ls /data/STRIPING/
create-image-file       mnt                     mnt0
mnt1


DEVEL# mdconfig -l -u md1
md1     vnode     512M  /data/STRIPING/stripe0
DEVEL# mdconfig -l -u md2
md2     vnode     512M  /data/STRIPING/stripe1
DEVEL# mdconfig -l -u md123
md123   vnode     512M  /data/STRIPING/stripe1

DEVEL# gmirror status
         Name    Status  Components
mirror/mirro0  COMPLETE  md2
                         md123

DEVEL# dd if=/dev/zero of=where-does-this-go bs=1m count=512
 
/mnt: write failed, filesystem is full
dd: where-does-this-go: No space left on device
431+0 records in
430+0 records out
450887680 bytes transferred in 67.178881 secs (6711747 bytes/sec)
DEVEL# 
 
 
This seems quite strange to me :) Its probably the way vnode disks are
attached
to the filesystem ?
