I want to make /dev/md7 out of sdb14 which is formatted EXT3 and is 86% full of data, plus sda14, which is identically partitioned but virgin space on a brand new HD replacing the old sda. I've already rebuilt /dev/md[0-7]. sdb14 was originally created using the excess of sdb's size over the size of the old sda.
On 11.4, I tried using YaST2 to do this, but it won't let me initialize md7 with only the old partition, and I see no clear indication that my data on sdb14 won't be eradicated by initially combining it with sda14 to create md7. [snip]
Without really thinking about the --create results, I did:
mdadm --build --verbose --force -n1 /dev/md7 --level=1 /dev/sdb14
The result was "mdadm: array /dev/md7 built and started."
Fsck says /dev/md7 is clean. Mounted, things seemed to be OK, but /proc/mdstat shows differently for md7 than for others:
md7 : active raid1 sdb14[0] 156280288 blocks super non-persistent [1/1] [U]
One issue might be that sdb14 doesn't have a superblock. --build is some sort of special option that doesn't create persistent superblocks, I don't think I've ever used it. -- Per Jessen, Zürich (6.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
