Hi!
I continue testing nilfs as a root file system. Until now I have no script to
cleanly unmount the root file system. (In the layered approach (aufs) I used
before this was not necessary.) So I just called sync and then shut down the
system.
The next boot took some time, because the superblock was "broken". Here an
extract from the kernel log:
[ 1.407323] NILFS warning: broken superblock. using spare superblock.
[ 1.408569] NILFS warning: broken superblock. using spare superblock.
[ 461.587031] segctord starting. Construction interval = 5 seconds, CP
frequency < 30 seconds [ 461.591873] NILFS warning: mounting unchecked fs
[ 461.629865] NILFS: recovery complete.
Is nilfs doing a sequential scan over the whole partition to find its spare
superblock?
Then I wanted to remove some snapshots:
> lscp -s

>rmcp 685
rmcp: 685: operation not permitted
What's the cause of this message? (rmcp also failed for all other snapshots;
the failed rmcp did not produce any kernel message)
Greetings, Michael
