redis: fix partial sync #63
Description
Currently on redis node restart, redis performs full resync from replica nodes. We should create fix to enable partial resync.
This is associated error:
1:S 09 Nov 19:48:19.265 * Partial resynchronization not possible (no cached master)
1:S 09 Nov 19:48:19.382 * SLAVE OF 10.3.245.174:6379 enabled (user request from 'id=11 addr=10.0.43.7:57700 fd=16 name= age=678 idle=0 flags=x db=0 sub=0 psub=0 multi=3 qbuf=0 qbuf-free=32768 obl=36 oll=0 omem=0 events=r cmd=exec')
1:S 09 Nov 19:48:19.385 # CONFIG REWRITE failed: Read-only file system
It seems like read only filesystem or too short terminationGracePeriod could be the cause.
