(Georgios)
- Fixing the last few remaining places where doing synchronous requests to QDB could lock up the namespace, and cause the MGM to become unresponsive for several seconds.
- Mostly related to FilesystemView, used by MGM services like Balancer, etc.
- (EOS-2610) PPS MGM hangs every day around 2pm for a couple of minutes, but recovers quickly. (No crash, just the NS remains unavailable) Almost sure it's related to the above, fixing that should also resolve this.
- seems not to be cronjob (internal?). Happens every 24h+30min.
- (have deleted some files on EOSPPS, will go below 3.5B to have some room for operations)
EOSBACKUP - want access to MGM machine for 1 day (to boot namespace), then tag release, then deploy new NS on that machine (is already on "citrine"). Will stop backup traffic tomorrow during the day, needs compacting (Georgios/Elvin/Kuba/Luca to coordinate).
