--- Comment #10 from David Sterba
btrfs: faild to read the system array on sda2 btrfs: open_ctree failed
means that there is a multidevice filesystem but the kernel module is not aware of all the devices (besides the one given to mount). Solution 1: run 'btrfs device scan' before the mount; this will scan all devices formated with btrfs filesystem Solution 2: explicitly name all the devices in mount options like: "mount -o device=/dev/sda1,device=/dev/sdb1,device=...,otheroptions /dev S1 is probably the best option as it's generic and you will not end up with unbootable system after you add a new device but do not add it to the mount option list (as would happen in S2 case). Documentation note: specifying a device just means that the kernel module will scan it and add it to it's internal list of known btrfs devices, but only devices belong to the mounted device (ie. the one holding the superblock and FSID) will be tied togather and mounted. IOW, adding any existing btrfs device will do no harm. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
