I started using the userman package this weekend on CCR1036-12G-4S-EM (6.11), and after only a few days it failed.
I get the error "failed to commit transaction: disk I/O error". After this happened I get "failed to add log: unable to open database file". It looks like this has caused the disk to switch to read-only, so other things like making a backup also fail.
Should I expect this service to work reliably? I'm only interesting in using radius authentication for routerboard logins, and thought it would be more convenient that a freeradius installation.
