Unable to start the database with this error after forceful server reboot - "system error cannot attach shared memory with segment_id"

Issue

• Due to filesystem errors, Filesystem was mounted with read-only. Unable to umount to run fsck on this filesystem, also unable to stop database which was accessing this filesystem which led to forceful server reboot. Then, fsck was performed and filesystem mounted back in read-write mode. However, progress database was unable to start with this error - "system error cannot attach shared memory with segment_id"
