Hi -
My primary node crashed today. I have had to reboot it but now it
reports unclean metadata. :(
# cat /proc/drbd

No usable activity log found. Do you need to create-md?
# drbdadm create-md r0
You want me to create a v08 style flexible-size internal meta data block.
There appears to be a v08 flexible-size internal meta data block
already in place on /dev/sdb at byte offset 4999945908224
Do you really want to overwrite the existing v08 meta-data?
[need to type 'yes' to confirm] no
I didn't confirmed the create-md process because I'm afraid that it will
discard all of the data saved on the disk, right?
And now, the icing on the cake: I currently have no secondary node due
to an hardware failure i faced a few days ago!
Is there still a chance that I can get my data back online on that
"standalone" drbd device?
Thanks in anticipation and best regards,
