All -
I am bringing up a custom board with an UBIFS root file system. The
board appears to boot fine and I am able to access files in the file
system. I have been debugging other issues and in the process I have
been powering off the board abruptly (i.e. turning off the power
supply), and hence the filesystem doesn't get unmounted correctly. The
filesystem recovers most of the time, but on multiple occasions I've got
the following error:
UBIFS: recovery needed
UBIFS error (pid 1): validate_ref: bud at LEB 31:93848 was already
referred
UBIFS error (pid 1): replay_log_leb: log error detected while replaying
the log at LEB 5:32
Obviously the filesystem wouldn't mount and my only option was
re-flashing the filesystem.
Can anyone tell me what might be happening, and how I can correct it?
The filesystem is being stored in Numonyx P30 NOR flash. The dmesg
output is as follows:
