UBIFS error ubi00 pid 7 make_reservation cannot reserve 160 bytes in jhead 1 error -30

This error message indicates that there was a problem reserving space in the journal head of the UBIFS file system. The error code -30 suggests that there may be a write error or a problem with the file system's internal data structures.

To troubleshoot this error, you can try running a file system check (fsck) on the UBIFS partition to identify and repair any issues. You can also try mounting the partition with the "nojournal" option to bypass the journaling system and see if that resolves the problem. If the issue persists, it may be necessary to backup and reformat the partition
