Error description
When chvg -G is run on a concurrent volume group, it throws the below error entries in errlog. IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION CAD234BE 0220223414 U H LVDD QUORUM LOST, VOLUME GROUP CLOSING F7DDA124 0220223414 U H LVDD PHYSICAL VOLUME DECLARED MISSING
Local fix
Problem summary
For conc-capable or other multi-node-varyon-protection enabled VGs, after converting the VG to Scalable Type VG, using chvg -G, these errors will be seen in the errpt: CAD234BE U H LVDD QUORUM LOST, VOLUME GROUP CLOSING F7DDA124 U H LVDD PHYSICAL VOLUME DECLARED MISSING But no further impact will be seen unless the VG only has a single disk in it. In this case, 'varyonvg' command will fail and have to be forced with -f flag. The reason is that the last step in chvg -G, to varyoff the VG, is initiating a metadata write to clear the 'varyon state' of the VG. This write goes to the end of the newly expanded metadata area on disk, but the LVM kernel does not yet allow metadta writes to go that far, and fails the write.
Problem conclusion
Correct chvg -G code to not try to clear the 'varyon state' of the VG, since it's not actually during chvg -G anyways. This avoids writing the metadata with the disk/driver in mismatched state, and avoids any errors.
Temporary fix
