Linux – fsck.ext4 unable to resolve UUID


While connecting remote iscsi storage I was getting above error.

This is the configuration of my iscsi server(target)

cat /etc/tgt/targets.conf

enter image description here

tgtd service is running in server side.

My client (initiator) configuration

First I tried this command

iscsiadm -m discoverdb -t st -p serverip -D

in client side it showing the target

fdisk -l

Disk /dev/sda: 2147 MB, 2147483648 bytes
67 heads, 62 sectors/track, 1009 cylinders
Units = cylinders of 4154 * 512 = 2126848 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0de5df58

After that I created a partition using that target and created filesystem also

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1        1009     2095662    5  Extended
/dev/sda5               1         506     1050900   83  Linux

I mounted using UUID in /etc/fstab using this option

UUID=751c022c-f670-46a8-940c-317c60eb65b8 /data ext4    _netdev         0 0

In client side iscsi service is running

[root@client ~]# chkconfig --list | grep iscsi
iscsi           0:off   1:off   2:on    3:on    4:on    5:on    6:off
iscsid          0:off   1:off   2:off   3:on    4:on    5:on    6:off

This is the UUID of /dev/sda5

[root@client ~]# blkid | grep /dev/sda5
/dev/sda5: UUID="751c022c-f670-46a8-940c-317c60eb65b8" TYPE="ext4" 

While rebooting client it's taking 3-4 minute to boot, and it's getting stuck in iscsi service and after 3-4 minute later it's showing this error

enter image description here

If I manually mount the target uisng this command its working

[root@client ~]# iscsiadm -m node -T -p -l
Logging in to [iface: default, target:, portal:,3260] (multiple)
Login to [iface: default, target:, portal:,3260] successful.
[root@client ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/vda2             6.9G  3.2G  3.4G  49% /
tmpfs                 372M  228K  372M   1% /dev/shm
/dev/vda1             194M   29M  156M  16% /boot
/dev/sda5            1011M   34M  926M   4% /data

How to solve this error and delay problem ?


This is from /var/log/boot.log message

Starting iscsi: iscsiadm: Could not login to [iface: default, target:, portal:,3260].
iscsiadm: initiator reported error (8 - connection timed out)
iscsiadm: Could not log into all portals

Best Answer

Client Side

Just Specify Initiator Name in this file /etc/iscsi/initiatorname.iscsi

Then it will work.
