Hi list, We had some stuck ops on our MDS. In order to figure out why, we looked up the documention. The first thing it mentions is the following:
ceph daemon mds.<name> dump cache /tmp/dump.txt Our MDS had 170 GB in cache at that moment. Turns out that is a sure way to get your active MDS replaced by a standby. Is this supposed to work on MDS with large cache size? If not, than a big warning sign to prohibit running this on MDSes with large caches would be appropriate. Gr. Stefan P.s. I think our only option was to get the active restarted at that point, but still. _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
