fsadm extending filesystem

[Carl Munnelly]

I have a filesystem with PE Size (32M).

I increased size to 100M actually extended to 128M to match PE size.
lvcreate -L 100 /dev/vg00/lvol21

I am now trying to extend file system using fsadm but having trouble.

used
fsadm -F vxfs -b 131072 /appl/uas (mountpoint)

This reports
fsadm -F vxfs -b 131072 /appl/uas
fsadm: /dev/vg00/rlvol21 is currently 32768 sectors - size will be increased
fsadm: attempt to resize /dev/vg00/rlvol21 failed with errno 28

You can get this message if you are trying to extend a filesystem that is 100% full. If that is the case, you must get the usage % below 100, to 98 or 99, and then try your fsadm command again.

I know you said you increased to 128MB but did you explicitly do an
lvextend -L 128 /dev/vg00/lvol21
before the fsadm. Your -b 131072 is consistant with a 128MB LVOL.

Yes, I'd forgotten about checking space in file system. That worked a treat. Moral of the story check space usage before starting.

Sounds to me as if your existing filesystem mount point is full, before trying to extend it. The error message you have (errno 28) indicates that there is no space left on device. You will have to reduce the size temporarily whilst you extend it.

Hi,

As said, if the filesystem is already at 100%, fsadm will fail. Reduce it to free up atleast 5%.

Did your lvextend command work ok?

Did you run :-

lvextend -L 128 /dev/vg00/lvol21

From your post it looks like you ran lvcreate not lvextend.

fsadm command looks ok.

Hi,
#define ENOSPC 28 /* No space left on device */

What size is that unit sector? Is that 512byte or a physical extent?
