I have a question about gjournal.
I have a system that I can not reparition/newfs and was wondering if it is
possible to add gjournal to the existing filesystems?
The system is i386, RELENG_6 and the disk are using gmirror and gstripe. The
partition I'm most interested in journaling is the gstripe parition.
Here's my fstab as a reference:
/dev/mirror/gm0s1b none swap sw 0 0
/dev/mirror/gm1s1b none swap sw 0 0
/dev/mirror/gm0s1a / ufs rw 1 1
/dev/mirror/gm1s1d /tmp ufs rw 2 2
/dev/mirror/gm0s1d /usr ufs rw 2 2
/dev/mirror/gm1s1e /var ufs rw 2 2
/dev/stripe/home /usr/home ufs rw,userquota,noauto 2 2
df -k:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/mirror/gm0s1a 2026030 104708 1759240 6% /
devfs 1 1 0 100% /dev
/dev/mirror/gm1s1d 2026030 13052 1850896 1% /tmp
/dev/mirror/gm0s1d 8122126 3859922 3612434 52% /usr
/dev/mirror/gm1s1e 8122126 1070764 6401592 14% /var
/dev/stripe/home 287190090 167354816 96860068 63% /usr/home
procfs 4 4 0 100% /proc
So lots of space free on the stripe. I read the man page for 7-Current but
it is unclear if a both the journal and data can exist in the same partition.
BTW, I've been using FreeBSD for almost 14 years now and I LOVE where 6 and 7
are going.
