Subject: (un)mounting takes a long time

Message-ID: <2929473.GGcWYBHif4@horus> (raw)

Hello!

I'm using ArchLinux with kernel Linux horus 3.10.5-1-ARCH #1 SMP PREEMPT. 
Mounting and unmounting takes a long time:

# time mount -v /mnt/Archiv         
mount: /dev/sde1 mounted on /mnt/Archiv.
mount -v /mnt/Archiv  0,00s user 0,16s system 1% cpu 9,493 total

# sync && time umount -v /mnt/Archiv
umount: /mnt/Archiv (/dev/sdd1) unmounted
umount -v /mnt/Archiv  0,00s user 0,33s system 1% cpu 23,247 total

fstab:

LABEL=Archiv    /mnt/Archiv             btrfs           defaults,compress=zlib 
0 0

Archiv is a RAID 0 comprised of two discs:

Label: 'Archiv'  uuid: b2504193-efeb-4ef3-8797-a8d73536a416
        Total devices 2 FS bytes used 1.99TB
        devid    2 size 2.73TB used 1023.01GB path /dev/sde1
        devid    1 size 2.73TB used 1023.03GB path /dev/sdd1

Are un(mounting) times like these normal?

Regards,
Florian
