sorry, we have renew install non-working node. but old cluster still show this pve5

hi you check image before we add success a Cluster but later we use public ip join in old Cluster . you see have error. we want remove out . but we use pvecm nodes no show this pve5 node. and we found join information have no click.

Hi we now have a trouble. xenserver use freenas raidz have write slow. but we building pve ceph cluster very fast. so we have way use pve ceph storage use 10G share xenserver . use ISCSI or NFS?

HI we want know pve have support auto config ip? if support how to config thanks.

thanks, oguz we have a new question if we use bound network 2*10G mode 802.3ad. switch need together config bond? or no config. if sw default support ,we how to test bond have ok?

Hi i remember have viedo have show how to use bond network 2*10G but i forget is which. we have see one by one 5.4 5.3 5.2 5.0 version still no found. if know please give me this viedo url thanks

and we have Ready intel ssd 1TB

thanks Alwin .let me add SSD test let you know.

and you think we before open writeback test have ok? face SATA if i add in 1 ssd per node in the testing server, will it improve the read and write speed?

okay. thakns , Alwin so we just undertand this right ? yeah SATA no SSD write and read good. if we use this plan A 3*node every node 2*osd every osd is 6TB sata plan B 5*node every node 5*osd every osd is 6TB sata plan C 5*node every node 3*osd every osd is 6TB sata you...

root@pve20:~# rados bench -p rbd 60 write -b 4M -t 16 --no-cleanup error opening pool rbd: (2) No such file or directory

use this? fio --filename=/dev/sdx --direct=1 --rw=randrw --refill_buffers --norandommap --randrepeat=0 --ioengine=libaio --bs=4k --rwmixread=100 --iodepth=16 --numjobs=16 --runtime=60 --group_reporting --name=4ktest or rados bench -p rbd 60 write -b 4M -t 16 --no-cleanup ?

and this is open writeback later test . you think ok?

every node all connect 10G switch . no use bond this is SATA enterprise disk.
