Proper way of doing a reboot of ISCSI server

[coffe]

Hi,
Due to some problems with my new storage server , i lost all my ISCSI/LVM host then storage server have been rebooted,
So Whats the proper way of shutting down the storage so proxmox servers will be able to connect again ?

a lvscan on storage shows the lv s.

*bump* as i dont like to redo all problems with my ISCSI server every time.
is it as simple as selecting disable om first LVM then ISCSI ?

Well my issue is identical.

I have 2 Proxmox servers, 1 ISCSI storage for backups.

I had the mount path in fstab, and as soon as i rebooted the master (which has the iscsi attached as well, along with the fstab line) it didn't boot properly, as he couldnt find the line i inserted in fstab.

had to remove, reboot, and then go to Proxmox GUI, storage, click on the iscsi setting i had there, then go for command line, "fdisk -l" (detected), and do the mounting.

I also saw a message "no iscsi records found", you having the same issue?

I use the recommend way of runnint LVM on top of iscsi , so proxmox it self handles it.
But by stopping all servers using it, then disable LVM then ISCSI , and reboot seems to work.

Will do more testing.

When you setup LVM it only allows content as Virtual Disks

I use the iscsi storage only for backups.

that being, i need to have vz backups or so, setting.

You get me here?

personnaly I'll do :
after having unmounted all iSCSI disks...

# vgs => to see the VG names on you iSCSI
# vgchange -an nameoftheVG => to disable the LV's and VG
# lsscsi (if you don't have it : # aptitude install lsscsi)

you'll see the disks :

neptune2:~# lsscsi
[0:0:8:0]    enclosu DP       BACKPLANE        1.05  -       
[0:2:0:0]    disk    DELL     PERC 5/i         1.03  /dev/sda
[1:0:0:0]    cd/dvd  HL-DT-ST DVD-ROM GDR-T10N 1.02  /dev/sr0
[3:0:0:0]    disk    DataCore SANmelody        DCS   /dev/sdb
[3:0:0:1]    disk    DataCore SANmelody        DCS   /dev/sde
[4:0:0:0]    disk    DataCore SANmelody        DCS   /dev/sdc
[4:0:0:1]    disk    DataCore SANmelody        DCS   /dev/sdd

now you need to remove the iSCSI disks :

# scsiadd -r 4 0 0 1 (of example)

check the tartget you're connected to :

neptune2:~# iscsiadm -m session
tcp: [1] 10.10.0.1:3260,1 iqn.2000-08.com.datacore:andromede1-applications

disconnect from iSCSI target :

# iscsiadm -m node -T iqnofyourtarget

you may now stop your iSCSI target

I hope it helps
