Hi Ryusuke,
>> 2) Can you mount the corrupted(?) partition from a recent version of >> kernel ?
this will take me some time to figure out
>> 3) Does read-only mount option (-r) work to avoid the crash ?
ro mount doesn't seem to crash
at least after mounting the partition read-only - running lscp - running sudo find . -type f inside the mounted partition - cat <some random file on the nilfs partition> does not crash
the crash i was seeing was during rsync (writing i guess)
Other info that might be relevant:
- the nilfs partition was on top of luks - the corruption happened probably during shutdown the shutdown hanged for a long time waiting for nilfs disk (iirc it waits for 1m30s) and even after that it did not finish so i turned the computer off without waiting further. after new start, i got the crash - i got the same problem on another disk recently
Regards,
Tomas
