iSCSI connection issue after upgrade to proxmox 9

[boomshankerx]

I just upgraded from proxmox 8 to 9 and none of my iSCSI LUNs can connect. Everything was working with proxmox 8. I'm using ZFS over iSCSI with TrueNAS 25.04.

kvm: -blockdev {"detect-zeroes":"unmap","discard":"unmap","driver":"throttle","file":{"cache":{"direct":true,"no-flush":false},"detect-zeroes":"unmap","discard":"unmap","driver":"raw","file":{"aio":"io_uring","cache":{"direct":true,"no-flush":false},"detect-zeroes":"unmap","discard":"unmap","driver":"host_device","filename":"iscsi://10.10.10.10/iqn.2005-01.com.example:proxmox/1","node-name":"OBFUSCATED","read-only":false},"node-name":"OBFUSCATED","read-only":false},"node-name":"drive-scsi0","read-only":false,"throttle-group":"throttle-drive-scsi0"}: Could not open 'iscsi://10.10.10.10/iqn.2005-01.com.example:proxmox/1': No such file or directory

I can ping the target and I can even add the target as iSCSI storage and see all the raw extents.

I could use a bit of help troubleshooting.

ChatGPT says "driver":"host_device" is incorrect in this context. Proxmox should be using "driver":"iscsi" for iscsi direct. Is this a bug or a problem with my config some how?

** UPDATE **
I managed to get everything working by doing apt reinstall -f proxmox-ve pve-manager libpve-storage-perl
Something was cleary stuck.
