Apologies, you are quite right, we only started using fail-over this year as of update 3278.

I have sent out logs to your support guys and hopefully they can spot something I haven't noticed.

hdparm stats look pretty slow, so maybe something wrong with underlying disks/array?


hdparm -t /dev/sda
*-----------------------------------------------------------------------------*


/dev/sda:
Timing buffered disk reads: 58 MB in 3.05 seconds = 19.03 MB/sec

*-----------------------------------------------------------------------------*
hdparm -t /dev/sdb
*-----------------------------------------------------------------------------*


/dev/sdb:
Timing buffered disk reads: 172 MB in 3.15 seconds = 54.64 MB/sec

No dropped packets or collisions on NICs as far as I can see.

Our 2nd box hdparm output looks a bit more healthy

/dev/sda:
Timing buffered disk reads: 4 MB in 4.03 seconds = 1016.08 kB/sec

*-----------------------------------------------------------------------------*
hdparm -t /dev/sdb
*-----------------------------------------------------------------------------*


/dev/sdb:
Timing buffered disk reads: 548 MB in 3.01 seconds = 182.19 MB/sec

*-----------------------------------------------------------------------------*
hdparm -t /dev/sdc
*-----------------------------------------------------------------------------*



Thanks
