Anyway, I'm trying out XFS with LVM2 using a 3-Ware 8006 Escalade. I had one aborted install where XFS forgot that it was supposed to be a file system. I saw some interesting kernel "oops" messages that I've never seen before too. A good time was had by all.
The current configuration (mostly for my own posterity's sake) is the basic Dell 670 w/ 2GB of RAM, 2 300GB SATA HDD's and 1 74G SATA HDD. The two 300's are on the Escalade controller. Mirroring on that device was problematic (slow mirror performance and no dirty region logging), so I'm using striping and rolling the dice that I'll get to replace the machine before one of the drives drops dead.
I've reconfigured from the basic "one big file system" approach back to a more reasonable :
- / = 16G
- /var = 13G
- /opt = 20G
- /work = 200G
- swap = 20G
> lvextend -L+8G /dev/VolGroup00/var
Followed up by :
# xfs_growfs /var
Did the trick quite nicely. So, OK - I'm liking lvm and xfs better and better.
