Hello
je viens d'essayer, il faut être en No Raid ? J'étais en Raid 0 j'ai eu ça :
root@retourjedi:~# umount /home
umount: /home: not mounted
root@retourjedi:~# nano /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda3 during installation
UUID=f3759fb2-c4a6-4a52-98c3-994edaee77e8 / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda2 during installation
UUID=c2cc613c-b75c-4be1-a980-f8171d2cfe4f /boot ext4 defaults 0 2
# swap was on /dev/sda4 during installation
UUID=3b9f07ad-13a0-4cbd-99ce-8f67d39a8137 none swap sw 0 0
root@retourjedi:~# pvcreate /dev/sda3
Can't open /dev/sda3 exclusively. Mounted filesystem?
Un avis ?
