Re: [Networker] Consistent 20% of expected throughput to DLT-V4 drive
2009-07-31 05:04:25
I'd first check if this drive is ok - stop networker, mount an empty (!!!)
volume manually and write to
the device with dd from /dev/zero (hope you are using some UNIX).
If you are not reaching the full LTO speed with variable blocksizes you have to
think over
connection/drive-HW issues.
If you are reaching the full LTO speed with this test, you'll propably have the
problem that your
networker - or better your networker clients - can not give the minimal data
rate the drive is needing
so it's getting in start/stop mode with degraded performance. In this case you
should think over
your parallelism settings or maybe try staging...
