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: LABEL=SWAP-sdb2 swap swap defaults 0 0 LABEL=SWAP-sdb3 swap swap...

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.

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 off the machine a...

In some scenarios I have experienced umount times higher than 15 minutes, even when there''s no pending IO (after a btrfs fs sync).

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. Nex...

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 patch to enable cgroup support
