Hi,

i have a cluster of 5 server connected (iSCSI) with a Synology RS3617xs+ (10GBE interface);

all seems working fine but on Synology i have some strange log:

continuous:

Code:

Do you have some hints about? I contacted Synology Support but without any results...
 
Hi,

Same problem here, with :
- 3 nodes cluster (pve-manager/5.1-46/ae8241d4 (running kernel: 4.13.13-3-pve))
- 4 x 1GbE nics by node,
- 2 x Synology RS3617RPxs (HA setup).
- iSCSI (4 paths)

Tons of logs like yours, everything seems to be working fine but I recently noticed a 6 times slower restore time (vs OMV 2 paths iSCSI)...

Thanks,

Christophe.
 
Hi,
try to contact synology support, i've no fortune with...

Synology support is ridicolous...no help about this problem...

don't change TARGET_THREAD_SET_COUNT, doesn't solve the problem...

do you have bond interfaces for synology node? I think problem is there...but i can't reconfigure my node for now, i'll try multipath or single interface on iscsi storage.
