Let's dissect this:
1) 3Ware
Optimization is key:
2) OS?
3) Openfiler
Openfiler is GREAT STUFF. Admin user is sensitive; i.e. you cannot change the admin user name. Also the tree permissions are picky for SMB shares and home folders:
So for instance, if this is your tree:
VG
LV
Folder1 <--- allocated as share, cannot be made homes folder
Folder2 <--- not allocated as share, can be made homes folder
I.E. any folders allocated as shares should not be listed for allocation to "homes"
Questions:
a) You are not using ZFS are you?
b) Are you using tracd?
c) What memory do you have allocated to openfiler?
d) Openfiler with USB devices and various kernel drivers has known issues with Volume allocation.
Solution: Load the volume group and logical volumes manually... fdisk -l shows the partition but lvm vgdisplay says "no volume groups found" [root@openfiler ~]# lvm vgdisplay
No volume groups found
[root@openfiler ~]# lvm lvdisplay shows the same message... So the next thing to do is to load the volume group manually.. [root@openfiler ~]# lvm vgscan
Reading all physical volumes. This may take a while...
Found volume group "rac" using metadata type lvm2
[root@openfiler ~]# Now that the volume group is loaded, the lvdisplay shows the logical volumes but they are in "NOT Available" status
[root@openfiler ~]# lvm lvdisplay
--- Logical volume ---
LV Name /dev/rac/crs
VG Name rac
LV UUID iKo4Jn-s2sX-pVda-RD8n-JxNr-EbiA-azLPIi
LV Write Access read/write
LV Status NOT available
LV Size 50.00 GB
Current LE 64
Segments 1
Allocation inherit
Read ahead sectors 0
[root@openfiler ~]# Now change the status of the volume manually
[root@openfiler ~]# lvm lvchange -a y /dev/rac/crs
[root@openfiler ~]# lvm lvdisplay
--- Logical volume ---
LV Name /dev/rac/crs
VG Name rac
LV UUID iKo4Jn-s2sX-pVda-RD8n-JxNr-EbiA-azLPIi
LV Write Access read/write
LV Status available
# open 0
LV Size 50.00 GB
Current LE 64
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:0
[root@openfiler ~]# If there are more logical volumes, manually change the status for each..
Long way around, but you could write a script for this, rather than reboot?
