So if you have a mount command that doesn''t use /etc/mtab then it will spit out a different device for the mounted device. So say we have SCRATCH_DEV_POOL="/dev/sda /dev/sdb /dev/sdc" we will turn this into SCRATCH_DEV="/dev/sda" SCRATCH_DEV_POOL="/dev/sdb /dev/sdc" and then when you mkfs this you do _scratch_mkfs $SCRATCH_DEV_POOL which turns into this

Hi all, I have two multi-disk btrfs filesystems on a Arch linux 3.4.0 system.

Hello all We are experimenting with btrfs and we''ve run into some problems. We are running on two Sun Storage J4400 Arrays containing a total of 48 1 TB disks. With 24 disks in the btrfs: # mkfs.btrfs /dev/sd[b-y] WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using adding device /dev/sdc id 2 ... adding device /dev/sdy id 24 fs

I have 2 SCSI disks each w/a RH 7.3 ext3 root filesystem: /dev/sdb1, and /dev/sdc1. /dev/sda1 is an old RH4.2 root filesystem. (sdb1 was created as an image of sdc1 using dd.) I have no problem booting from a SYSLINUX 1.52 floppy with SYSLINUX.CFG containing "append initrd=initrd.img root=/dev/sdb1". When I alter SYSLINUX.CFG with: "append initrd=initrd.img root=/dev/sdc1".

Hi, I have added 2x2Tb to my existing 2x2Tb raid 1 btrfs filesystem and then ran a balance: # btrfs filesystem show Total devices 4 FS bytes used 1.74TB devid 3 size 1.82TB used 0.00 path /dev/sdd devid 4 size 1.82TB used 0.00 path /dev/sde devid 2 size 1.82TB used 1.75TB path /dev/sdc devid 1 size 1.82TB used 1.75TB path /dev/sdb # btrfs

Hello, I have a Promise EX 12-port RAID controller in my box, connected to 8 750GB disks. I have set up 2 RAID-5 devices and joined these using LVM. This is working fine. However, there is something that seems wrong.. (4-1) * 750 = 2250, but df reports the LVM volume as a mere 4.0T; /dev/mapper/storage_volume-stor 4.0T 3.6T 507G 88% /storage Shouldn't this be 4.5TB? Relevant bit of

We currently set sb->s_flags |= MS_POSIXACL unconditionally, which is incorrect -- it tells the VFS that it shouldn''t set umask because we will, yet we don''t set it ourselves if we aren''t using POSIX ACLs, so the umask ends up ignored.
