Hello community! There are two servers with one shared storage system via FC. I set up a shared LVM and a multipatch. I have doubts that everything is configured as needed. Proxmox version 7.4-3

multipath.conf
defaults {
polling_interval 2
path_selector "round-robin 0"
path_grouping_policy multibus
uid_attribute ID_SERIAL
rr_min_io 100
failback immediate
no_path_retry queue
user_friendly_names yes
}

blacklist {
wwid .*
}

blacklist_exceptions {
wwid "3600000e00d2c0000002c0c2e00000000"
wwid "3600000e00d2c0000002c0c2e00010000"
}
multipaths {
multipath {
wwid "3600000e00d2c0000002c0c2e00000000"
alias vmdisk
}
multipath {
wwid "3600000e00d2c0000002c0c2e00010000"
alias vmbackup
}
}
vmbackup (3600000e00d2c0000002c0c2e00010000) dm-31 FUJITSU,ETERNUS_DXL
size=10T features='1 queue_if_no_path' hwhandler='1 alua' wp=rw

`- 12:0:0:2 sdc 8:32 active ready running
vmdisk (3600000e00d2c0000002c0c2e00000000) dm-30 FUJITSU,ETERNUS_DXL

I moved a number of vm with disks to these nodes, they were positioned very strangely. Some went straight to the sdb disk, some went to the vmdisk (multipath).

I also made changes to /etc/lvm/lvm.conf. However, I don’t understand why this is needed, that’s what was recommended in the setup articles. Can you explain why this is needed?
Code: 
filter = [ "a|/dev/mapper/vm.*|", "r|.*|" ]

After moving all VMs to the first node, lsblk looks like this

You will see a difference if you run pvs for example. Revoking access to the underlying block storage will prevent duplicates.

It does seem strange. Did you create LVM after configuring multipath and use mpath device for PV, or is there a chance you used sdX at some point and did not clean it up properly?
What does your /etc/pve/storage.cfg contain?
What about "pvs ; vgs ; lvs" ?
And : pvscan, vgscan, lvscan

As for the filter line, you'd have to ask the author of the guide you followed why they recommended such line. The description is in the man page and the lvm.conf itself:
Configuration option devices/filter.
# Limit the block devices that are used by LVM commands.
# This is a list of regular expressions used to accept or reject block
# device path names. Each regex is delimited by a vertical bar '|'
# (or any character) and is preceded by 'a' to accept the path, or
# by 'r' to reject the path. The first regex in the list to match the
# path is used, producing the 'a' or 'r' result for the device.
# When multiple path names exist for a block device, if any path name
# matches an 'a' pattern before an 'r' pattern, then the device is
# accepted. If all the path names match an 'r' pattern first, then the
# device is rejected. Unmatching path names do not affect the accept
# or reject decision. If no path names for a device match a pattern,
# then the device is accepted. Be careful mixing 'a' and 'r' patterns,
# as the combination might produce unexpected results (test changes.)
# Run vgscan after changing the filter to regenerate the cache.

So your line says: reject/ignore all paths except those that start with /dev/mapper/vm. I dont see much value in it given your screenshots.
A reboot of both nodes may help you clear out any stale config.

Good luck

no, these were blank disks, then I created a LVM and attached it to the storage, then transferred the disks

Are you using a Clustered Filesystem here?

the question is - when was multipath introduced? In any case LVM/iSCSI+Cluster requires a delicate balance, that is easy to upset by poking the backend and changing the configuration.
The LVM slice will only activate on a node when a VM is running there, it wont deactivate on move. So the view you will see may be different from day 1 to day 31, not all Warnings need to be or can be fixed.
