[linux-lvm] Any known problems with ReiserFS and LVM?

[linux-lvm] Any known problems with ReiserFS and LVM?

[Michael Boman]

Is there any known problems with ReiserFS and LVM, or doesn't LVM care
at all about what filesystem it's using? If so, will it work with RAW
devices as well?

Please advice

We have been using LVM with reseirfs for well over a year now. Works
fine.

As Patrick Boutilier pointed out ReiserFS works fine with LVM.
Basically LVM is transparent to any Filesystem/Database System etc.

ReiserFS needs special support to work on LVM snapshots though.
Chris Mason and I created a VFS extensions which even allows ReiserFS
to be mounted on LVM snapshot logical volumes.
Hopefully this patch will make it into 2.4.0.
BTW: it will be included in LVM 0.9.
It is (not yet) available for 2.2 though.

Talking about RAW device support, Stephen Tweedies raw device patch 
allows you to bind a character device to _any_ block devices
(including LVM) to provide genuine Unix raw character device semantics.

2.4.0-textX contains it.

There's a raw device support patch for 2.2.17 available at
ftp://ftp.kernel.org:/pub/linux/kernel/people/sct/raw-io/
