Dear zfs fellows, during a specific test I have got the impression that scrub may have quite an impact on other I/O. CIFS throughput is down to 7 MB/s from 100 MB/s while scrub on my main NAS. That is not a surprise as scrub of my raidz2 pool maxes out CPU on that machine. (1 Xeon L5410). I am running scrubs during week-ends, so this is not a problem. I am asking myself however what will happen on larger pools where a scrub pass will take days to weeks. Obviously, zfs file systems are much more scalable than CPU power ever will be. Hence, I am seeing a requirement to manage scrub activity so that trade-offs can be done to maintain availability and performance of the pool. Does anybody know how this is done?
Thanks in advance for any hints, Regards, Tonmaus -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
