Hello all,
We have two nodes with drbd8.2.5 installed (redhat AS - kernel
2.6.23.12 and debian etch - kernel 2.6.22).
My primary node (debian etch) needed to be halted for some time, so I
put the secondary node on primary state and run my services without
any problem.
When the other (debian etch) node become active, the resync cause a
high load average on the redhat node (~= 130).
Suspecting of low I/O's capacity and my application having hard write
on disk, I've tried to reduce the transfer rate from 100M to 30M but:
# drbdadm adjust -d resource
7018381312s: out of range
Out of range?!?
I decided to pause the resync process until this question is answered..
Thanks in advance!
