Hi,
I am seeing a weird issue with the sync speed as reported in /proc/drbd
...
[==>.................] sync'ed: 18.1% (1258325/1535953)M
finish: 3:03:47 speed: 116,824 (111,092) K/sec
^^^^^
@111 MB/sec , 1.5 TB should xfr in ~30 min , yet it's saying hours !
I xfr'd files over the NFS @ 130 MB/s using the same replication link,
during DRBD sync, vnstats reports:
average 3.09 MB/s | 116.48 MB/s
so the link is good.
hdparm clocks my array's buffered disk ( not cache ) speed at 380 MB/s ,
so the problem is not the array.
I'm quite puzzled here... Anyone has an Idea why this is happening ?
