I was playing with evms (2.2 kernel 2.6.3 vanilla) and some reason, it
grabbed my usb disk (sde) and won't let go of it. Is there any way I can
make it let go of the disk? It grabbed sde1 and sde2 of the disk.
I tried the deactivate which just gave me an invalid argument. I really do
not wish to reboot this machine just to remove the usb disk.
I also noticed it wanted to grab my partitions on sda which were already
mounted and couldn't grab them.

You can put entries in your /etc/evms.conf file to tell EVMS to ignore certain
disks (e.g. if you don't want it to examine sde). See the "legacy_devices"
section (for 2.4 kernels) and/or the "sysfs_devices" section (for 2.6
kernels).

If you have the "dmsetup" tool, you can issue a "dmsetup remove_all" command
to deactivate all the DM devices. Just make sure all the DM devices are
unmounted, or it won't actually release the underlying disks. Dmsetup is part
of the device-mapper package, available at ftp://sources.redhat.com/pub/dm/.

Again, you can add an "exclude" entry in your /etc/evms.conf if you want EVMS
to ignore sda. Otherwise, have a look at

Ok, great, that works.

Ahh, thanks. That did the trick.

I think I'll only give it disks that I want in evms. The "sde" is a USB
disk that I move around alot.
If you're not the right person to ask, please direct me to someone else.
I was going to do a raid5 across a few disks (this is in the future not
now). Is there any way to add disks to that raid5 using evms?

I'm one of the right people to ask about EVMS. Please send questions to
[email protected] and the whole group will be able to provide
assistance.
EVMS will recognize and manage software raid devices, but currently doesn't
support expanding raid-5 devices. It's on our list for later this year. I
believe there's a stand-alone tool available that will let you do this
(google for raidreconf).
