Here's the applied yaml:

Here's the commands I ran on the mgr pod toolbox:

efscli system init
efscli cluster create cltest
efscli tenant create cltest/test
efscli bucket create cltest/test/files-iscsi -s 512K -r 2 -R 1 -t 1
efscli service create iscsi files-iscsi
efscli service serve files-iscsi cltest/test/files-iscsi/lun1

I've applied weavenet and the kubernetes dashboard but besides that, this is a fresh cluster (has been rebooted though).

[ERRO] [node4] [Driver] [grpc] rpc error: code = Internal desc = mount failed: exit status 32

hi! I am trying to mount pv to pod with help of NFS dynamic provisioning and met problem during mounting process.
Error:
Jan 5 21:13:43.214 [ERRO] [node4] [Driver] [NodePublishVolume()] Failed to mount volume 10.174.65.38:/nfs/pvc-c26498bd-c3c5-4a5a-b946-57b4c1179f55. Error: mount failed: exit status 32

iSCSI support for multi-path provisioned LUNs

With this functionality, CSI provisioner would setup md capable LUN that consists of 2+ EdgeFS block devices.

Enhanced performance. This would provide an additional performance boost by spreading I/O across 2+ paths.
Enhanced reliability. This would enable local to container RAID group rebuilds.

Edgefs service comes to inoperable state

During CSI ISCSI testing, edgsfs iscsi service may stuck in inoperable state
Cluster definitions

efscli cluster create cltest
efscli tenant create cltest/test
efscli bucket create cltest/test/bk1
efscli service create iscsi iscsi01

Steps to reproduce:

Create Objects

#!/bin/bash -e
LIMIT=30

for ((a=1; a <= LIMIT ; a++))
do
   efscli object create cltest/test/bk1/lun$a -s 128K
done

Create exports

#!/bin/bash -e
LIMIT=5

for ((a=1; a <= LIMIT ; a++))
do
   efscli service serve iscsi01 cltest/test/bk1/lun$a
done

Login to target via iscsiadm and format disks
Unlogin from target
Delete all exports

#!/bin/bash -e
LIMIT=30

for ((a=1; a <= LIMIT ; a++))  
do
  efscli service unserve iscsi01 $a@cltest/test/bk1/lun$a
done

Delete luns

#!/bin/bash -e
LIMIT=30

for ((a=1; a <= LIMIT ; a++))
do
   efscli object delete cltest/test/bk1/lun$a
done

7 Neadm service restart iscsi01
8 Repeat from step 1
On second iteration we could stuck with IO errors via neadm or efscli commands
