Ubuntu Server 22.04 can only see one IronWolf 4TB drive, after installing a second

mx flag

My 6 disk ZFS array had a drive go out the other day. It was built on all HGST 2TB DeskStar HDDs. I decided I would slowly double the size of the all drives after replacing the first one, and eventually rebuild the array once I had replaced all the 2TB HGSTS drives with 4TB Seagate IronWolf drives.

I replaced the bad HGST drive with a 4TB IronWolf CMR drive and the pool rebuilt itself fine (Yes I know the sector size isn't right, but I need storage, not performance for now). I am now trying to replace another drive with another 4TB IronWolf but Ubuntu doesn't see it.

If I run sudo ls -l /dev/disk/by-id | grep ata-ST4* I only see the first drive I put in the array. No other IronWolf drives show up.

Running sudo lsblk|grep disk with 2 IronWolf drives I get:

When I take the second IronWolf out and run sudo lsblk|grep disk I see:

Why would Ubuntu be unable to see that second IronWolf drive?

Not sure why I didn't think of this sooner, but I have a USB HDD dock. I hooked it up to my main Windows computer so I could see if Windows could see either of the two remaining drives. Windows unable to see one of them at all, and the other one was visible but Windows was unable to create a partition table on it. Based on that it was pretty obvious that both drives were bad.

I've avoided Seagate drives for years, and after deciding to give them a try again, 2 out of the 3 I bought were defective. Not good reintroduction to Seagate...

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
