Description

Space is not reclaimed during a garbage collection or leaf coalesce operation.

SMlog reports "No space to leaf-coalesce... but enough space if skip snap-coalesce"

Resolution

The error indicates that the SR is almost 100% full and there is no space on the SR to run coalesce cycles.

You can attempt one of the following solutions:
  • Shut down the VM and then do a leaf coalesce on it.
  • Expand the SR. After the SR is expanded, the coalesce process runs successfully and reclaims the space.

Problem Cause

Free space on SR was 1GB. Space was not reclaimed back to SR as the coalesce process was unable to run the cycles due to insufficient space.
