Subject: [PVE-User] DeviceMapper devices get filtered by Proxmox
Date: Thu, 20 Jul 2023 14:21:05 +0200 [thread overview]
Message-ID: <2b5b83bb-c90e-b6dd-4b15-a57414b42542@gmail.com> (raw)
Dear all,
I'd like to use some existing hardware to create a Ceph cluster. Unfortunately, all my external
disks are filtered by the WebUI and by pceceph command which prevents using them as OSD disks.
My servers are connected to a SAS-JBOD containing 60 SAS-HDDs. The connection is done via 2
dual-port SAS-HBAs, each port connecting to both of the JBOD controllers.
This means that all my external disks can be reached via four SAS-path and thus I see 240 disks in
/dev. (Actually, I see 244 /dev/sd* devices as there are also 4 internal disks for the OS…)
Using multipathd, each disk with its four entries in /dev is available a fifth time in
/dev/mapper/${WWN} which is a symlink to /dev/dm-${NUMBER}.
Both /dev/dm-${NUMBER} and /dev/mapper/${WWN} entries are filtered by Proxmox.
Is there a way to remove this filter or to define my own set of filters?
Using the /dev/sd* entries would be possible but I would loose the redundancy provided by multipathd.
Regards,
Uwe
