2020-07-12T10:58:21.732180Z 0 [ERROR] InnoDB: ./ib_logfile0 can't be opened in read-write mode.

The most likely root cause are the permissions on the $SPECROOT/mysql/data/ib_logfile0 file


Release : Any

Component : Spectrum Core / SpectroSERVER


Check the permissions on the mysql files. They should be owned by the user/group that owns the Spectrum installation. Change as needed.
