[SOLVED] Error creating LVN on iSCSI: device is partitioned

tippers · Tuesday at 13:37

I'm migrating from ESXi to PVE using two hosts/nodes and shared iSCSI storage. The iSCSI is setup with multipath and the first four LUN's have been created successfully.
The last LUN is not allowing me to create an LVM disk though with the following error:

create storage failed: pvcreate '/dev/disk/by-id/scsi-3690b11c0000238a20000030e5098c67b' error: Cannot use /dev/disk/by-id/scsi-3690b11c0000238a20000030e5098c67b: device is partitioned (500)

When I'd migrated all of my VMs from ESXi to PVE, I didn't delete the last datastore and instead left the VMware partition in place when it was connected to PVE. I've since reinitialized the disk on the SAN and removed the partition using fdisk on the node.

lsblk now shows the following output:

Any thoughts on why the error message appears?

bbgeek17 · Tuesday at 16:25

The output shows 8 paths to the LUN, is this what you expected?
What does "multipath -ll" show? What about "fdisk -l [/mpath_device]" ?

Yes 8 paths. Two network cards in each host, two switches and two SAN controllers.

multipath -ll shows:

Have you yet retried: pvcreate /dev/disk/by-id/dm-uuid-mpath-3690b11c0000238a20000030e5098c67b ?
Have you rebooted the server since detecting the error?

Same error, The device is partitioned and I have rebooted since the error first appeared yesterday.

When it first happened, I deleted the partition using fdisk but when that didn't work I reinitialized the disk on the SAN.
When I run fdisk /dev/mapper/3690b11c0000238a20000030e5098c67b

Code:

root@pve1:~# fdisk /dev/mapper/3690b11c0000238a20000030e5098c67b

Welcome to fdisk (util-linux 2.41).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

The device contains 'gpt' signature and it will be removed by a write command. See fdisk(8) man page and --wipe option for more details.

Device does not contain a recognized partition table.
The size of this disk is 3.3 TiB (3597530038272 bytes). DOS partition table format cannot be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).

Created a new DOS (MBR) disklabel with disk identifier 0xe9920e76.

Command (m for help):

It's recognised as containing a 'gpt' signature. But when I run fdisk /dev/mapper/<one of my other LUNs>
The output shows that it contains a LVM2 member.

bbgeek17 · Tuesday at 17:36

Give "wipefs -a /dev/mapper/3690b11c0000238a20000030e5098c67b" a try.

Bingo - many thanks for your help

bbgeek17 · Tuesday at 18:00

You are welcome.

The error you were receiving was somewhat generic. The tool was upset about the label/signature, not a partition:
