[LU-15493] facet_failover () and wait_clients_import_state() improvements

Sat, 11 Jun 2022 15:38:27 +0000

Patch contains the following proposed fixes and improvements:

Fix template matching in affected facets accounting (when the == and != operators are used, the string to the right of the operator is considered a pattern);

Reduce failover duration done by facet_failover(): Long failover duration needs increasing of ldlm_enqueue_min to avoid evictions with striped objects, so let's do node reboot and mount on failover node in parallel.

Make wait_clients_import_state() working with a facet list;
