WARNING: volume: failed to enable JRM, no available NVURM space, class=class
Explanation
Resuming just resynchronization process on volume volume was unsuccessful. If volume is the mirror volume, resynchronization copying of the whole volume is performed after a panic occurs.
The following potential causes can be considered:
a) A disk malfunction occurred and there are an insufficient number of normally operating disks which can store the logs (NVURM) for the Just Resynchronization Mechanism (JRM).
b) The size of the private slice of the class class is insufficient and it is impossible to store the logs (NVURM) for the JRM to the private slices.
If one has added to the class a disk with a capacity larger than the disk first registered to the class, it is possible that b) is the cause. For details on insufficient private slice size, refer to "A.2.7 Disk Size."
Resolution
Check the disk status within class. If a disk failure has occurred, identify the cause by referring to disk driver log message, and recover the disk.
If volume is not a mirror volume (such as a single volume), the Just Resynchronization Mechanism is not necessary. This being the case, if volume is not a mirror volume and the cause is b), turning the volume's JRM attribute to off or ignoring this message poses no problems. For turning the JRM attribute off, refer to "D.7 sdxattr - Set objects attributes."
WARNING: volume: failed to retrieve NVURM from disk disk, class=class
Explanation
NVURM read request of volume from disk was unsuccessful. Just resynchronization will switch to copying of the entire disk.

WARNING: class: unknown class file found
Explanation
Class file class which does not exist in class database file was found while booting the system.
This message is output if starting a node at the time that all disks registered in the class cannot be found due to disk array case down or cable disconnection.
Resolution
Add class which is output at the message to /etc/opt/FJSVsdx/sysdb.d/class.db so that this message will not be output.
Example) If class is class0001
Add class0001 at the position before "# Disk Class List."
# cat class.db class0001 <--- Add # Disk Class List
WARNING: invalid configuration database ID information, sdxerrno=sdxerrno, class=class:
