unrecoverable crash #153

Open crodwell opened 6 years ago

Hi, still having an unrecoverable crash issue intermittently. I cannot restart riofs without first running an umount on the directory. I managed to harvest a verbose log right before a crash; not sure it's of any help:

Hello, without any additional logs I can't tell you for sure what happened.

This log says that for some reason "Mountpoint /d1/s2s/s3/optimus does not exist". Could you please check if any other running script removes this mount or folder?

Hi, how could I get some additional logs? This verbose setting writes GB's to disk.

The mount point exists, it just gets tied up by RioFS somehow.
Once it's finally crashed, I cannot restart RioFS until I umount. However doing an umount too soon; gives this: umount: /d1/s2s/s3/optimus: target is busy (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).)
