Issue

The root volumes (vol0) on both nodes are lack of free space, but without any core files or packet trace data.
VLDB data on node-01 grows to gigabyte level.

node-02 may have a corrupt flag due to failed RDB data synchronization from node-01 (for example, after BIOS and BMC firmware updates).

bootarg.rdb_corrupt="7050055000"

CIFS access may be affected if the situation gets worse and the whole cluster doesn't work normally.
