how to create label fo swap space
I just add a partition /dev/sdb3 and use "mkswap
/dev/sdb3" to make it swap space. How can I label the
/dev/sdb3 like "SWAP-sdb3"?
what I want is put on /etc/fstab as entry like:

Can't resize second device in RAID1
Hi,
the situation:
Label: ''RootFS'' uuid: c87975a0-a575-405e-9890-d3f7f25bbd96
Total devices 2 FS bytes used 284.98GB
devid 2 size 311.82GB used 286.51GB path /dev/sdb3
devid 1 size 897.76GB used 286.51GB path /dev/sda3
RootFS created when sda3 was 897.76GB and sdb3 311.82GB.
I have now freed other space on sdb. So I deleted sdb3 and recreated
it occupying all available space.

[PATCH] Btrfs: fix sync fs to actually wait for all data to be persisted
...work to finish before returning success to the
caller. This change fixes this, ensuring that there''s no data loss
if a power failure happens right after fs sync returns success to
the caller and before the next commit happens.
Steps to reproduce the data loss issue:
$ mkfs.btrfs -f /dev/sdb3
$ mount /dev/sdb3 /mnt/btrfs
$ perl -e ''$d = ("\x41" x 6001); open($f,">","/mnt/btrfs/foobar"); print $f $d; close($f);'' && btrfs fi sync /mnt/btrfs
Right after the btrfs fi sync command (a second or 2 for example), power

[PATCH] Btrfs: fix very slow inode eviction and fs unmount
...lits of extent_state structures, which
consume a lot of time and cpu when the inode has many pages. In
some scenarios I have experienced umount times higher than 15
minutes, even when there''s no pending IO (after a btrfs fs sync).
A quick way to reproduce this issue:
$ mkfs.btrfs -f /dev/sdb3
$ mount /dev/sdb3 /mnt/btrfs
$ cd /mnt/btrfs
$ sysbench --test=fileio --file-num=128 --file-total-size=16G \

RAID + LVM Addition to CentOS 5 Install
Hi All,
I have what I believe to be a pretty basic LVM & RAID setup on my
CentOS 5 machine:
Raid Partitions:
/dev/sda1,sdb1
/dev/sda2,sdb2
/dev/sda3,sdb3
During the install I created a RAID 1 volume md0 out of sda1,sdb1 for
the boot partition and then added sda2,sdb2 to a separate RAID 1
volume as well (md1). I then setup md1 as a LVM physical volume for
volume group 'system'. I left the sda3,sdb3 partitions available for
future use.

Utility tool for dm-ioband.
Hi everyone,
I made a utility tool for dm-ioband version 0.0.4, named iobandctl.
It enables you to easily apply I/O bandwidth control to an entire disk,
and manage it. It helps you set the percentage of bandwidth
to give each partition, and each user, process, group, or cgroup.
(You are not able to use cgroup support yet, because the dm-ioband

They both have three partitions setup as RAID1 using md (boot, swap,
and an LVM data partition).
# cat /proc/mdstat

umount-ing and even power cycling, they're in the wrong place.

I =am= taking into account differences like Ubuntu recognising it as

Any ideas?
