We have something like this on z/OS Unix. It does not work as well as you
might think. All it does is push the space problems out to the volume level.
We end up having to un-mount the filesystem, move it to a new volume, and
re-mount it.
I would vote to not do this on Linux.

Obviously the by-id/by-path debate has been of fairly major concern on

Clearly, also, no distributor is interested in fixing it for the

If you're talking about a VG that has free space and a script smart enough

too hard.

If you have disk sitting around that you could add to the VG then why not add
them to the VG when you create it, and make the filesystems large enough that
they don't need to grow?

That was my first thought too... BUT - I can see how it could be useful to
have free space in a VG and then assign it where it might be needed as it's
needed within the VG. (Leave 1GB of the VG unassigned, and let the script
assign it on an 'emergency' basis to the LV that is running low).
Thanks for the info. I'm going to discuss this further with management.

Is it possible to shrink a LVM fs, not just grow it?

I have problems with this kind of thing on z/OS Unix. Our /tmp filesystem on
z/OS is nearly a full volume with usage around 2% because DB2 was configured to
write a log file to /tmp, and someone ran a load test that cause DB2 to write
1.2G of log data.

This seems odd to me. If I were the user getting charged by the amount of
space I would not want it to grow without being told I was going to be charged
more.

It depends on the filesystem. Some can shrink and some can't. Also some can
shrink only if there are no used blocks in the area that is going to be removed.

We are mainly an EXT3 shop. I know z/VM can grow an LVMd EXT3 fs, just not
sure if it has the ability to shrink it.

See lvreduce .. also vgreduce (but you can only remove unused physical
volumes which ain't always easy). If you do a 'man lvreduce' it will
caution you that you need to resize the filesystem before you resize the
LV.. pay attention to that :-)
