I went to add a new nic to my TrueNAS server, and after doing so noticed my main pool showed half the vdevs unassociated. I moved the card back to the original PCI slot and now the pool is back. Has anyone seen this before ? TrueNAS-SCALE-23.10.1

[image] majerus: I moved the card back to the original PCI the slot may look x16 but depending on what is plugged where, the motherboard will make them electrically x8, x4 or x1 !. To know for sure you’d have to read the motherboard’s caveats ( I mean manual ) So yes, nothing new :frowning: …

This info was in my signature, ill add it back guess havent done that since forums switched… Motherboard is Supermicro X11SSM-F Card was originally in CPU SLOT7 PCI-E x8, moved it to Slot 4 which looks like x4 MNL-1785.pdf 5.67 MB So does the addressing of…

Thanks for the info, appears this is what happened. Why do the lanes matter, i thought metadata was written to each drive for zfs to recognized which drives belong to which vdevs, and therefore pools. Thanks!

[image] majerus: … Why do the lanes matter (hardware) , i thought metadata (software) … Two different beasts.

There has to be more to this, ill google it…

Is the HBA recognised by Truenas in the new slot ? lspci -v I didnt read the manual, but maybe it gets deactivated when using other slots/sata lanes.

[image] majerus: So does the addressing of the disk get lost when changing slots? I thought zfs wrote metadata on the drives so if they move around it doesnt matter? AFAIK ZFS vDevs can be registered either with a device name e.g.: # zpool status -v boot-pool pool: boot-pool state: ONLINE…

Somewhere I think I missed is the make/model of the HBA you are using. It is important. If your HBA requires 8 PCIe lanes and you moved it into a 4 PCIe lane slot, that of course makes a difference. If this is the case, you can use slots 6 or 7 only unless the HBA can be configured to use 4 PCIe …

The card is an LSI 9211-8i. Here is the pool in its current working state appears to guid. I might move this card again and see if its just not populating or what the deal is. state: ONLINE status: Some supported and requested features are not enabled on the pool. The pool can still be u…

Moved HBA to new PCI slot, half my drives show vdev not associated

Could be motherboard related - maybe when you put things into the second pcie slot the first gets less lanes or something.

Hard to tell without your hardware…
