Hello I have a flesystem that has run out of space. I have tried using the following command to add space:
# chfs -a size=+100 /lsrc
I get the following error:
0516-404 allocp: This system cannot fulfill the allocation request.
There are not enough free partitions or not enough physical volumes
to keep strictness and satisfy allocation requests. The command
should be retried with different allocation characteristics.
Is there a way to add more space to this filesystem?
Thank you
David
Hi,
you first have to verify if there is some free space in the volumegroup, use:
lsvg <volumegroup name>
check Free PP's as this is the maximum size the filesystem can be increased to.
It does not look like there is much space. How do I see what disks are available to add to this vg?
# lsvg vg01

lspv show assigned and unassigned disks, but you're output shows that there is 896MB available so the command chfs -a size=+100M /lsrc should increase the filesystem with 128MB (if it's located in vg01)
dkranes - pls post the output of 'lsvg -l vg01' and 'lsvg -p vg01'. My guess is the logical volume is setup as RAID 1 (mirroring).
If I do a lsvg -l vg01 it shows
lsvg -l vg01
vg01:

I tried the following:
# chfs -a size=+100M /lsrc
and received this error:

Just as I thought, /lsrc is mirrored (as is all of the other normal filesystems except oracle11g). You can tell this by looking at the number of LPs (logical partitions) and the number of PPs (physical partitions). When a filesystem is mirrored the PPs will be twice what the LPs are. The mirrored physical partitions must be on separate physical drives. If you don't have any more disks to add to vg01 then you either have to shrink a filesystem or move it to a different volume group.
Oops - missed /gerfs, it's not mirrored either.
I did shrink a few other file systems and then I was able to add enough space. Thank you for you help.
David
you probably dont have space for mirroring as /lrc is mirrored. Check the manpage of migratelp and migrate one lp of an unmirrored filesystem onto the other disk and then you wil be able to increase the filesytem by atleast 128MB i.e. 1 PP size.
