Problem increasing filesystem 1

[terrywashington]

I am attempting to increase the size of a filesystem by 1GB. The system is running AIX 5.2. I ran the lsvg command to verify that there is available space and received the below error. The datavg consists of two 36GB disks that are not mirrored. What am I missing here?

# lsvg datavg
VOLUME GROUP: datavg VG IDENTIFIER: 00068f8c00004c00000000f
bf41b7a26
VG STATE: active PP SIZE: 64 megabyte(s)

I think you need to use a larger PP size (>64MB) in order to get round the 512 limit

I'm sure someone else will come up with a more comprehensive explanation

use

smit chlv1

F4 to select the VG your Filesystem is in.

Then change the number of logical partitions

1 LP = PP Size (64Mb in your case)

It doesn't matter to much stick 1024 in

Now extend your FS

Thanks Mike. That worked!

Do smit chlv on the logical volume and then
increase MAXIMUM NUMBER of LOGICAL PARTITIONS. The default
is 512 which you also see in the errmsg.
