I started installing the SAS version of these drives two years ago in our cluster and I haven't had one fail yet. I've been working on replacing every spinner we have with them. I know it's not helping you figure out what is going on in your environment but hopefully a "the drive works for me" data point helps somehow.

Subject: Anyone else having Problems with lots of dying Seagate Exos X18 18TB Drives ?
Hi,
I am using Seagate Exos X18 18TB Drives in a Ceph Archives Cluster which is mainly
write once/read sometimes.
The drives are about 6 months old.
I use them in a ceph cluster and also in a ZFS Server. Different Servers
(all Supermicro) and different controllers but all of type LSI SAS3008
In the last weeks these drives are experiencing massive read errors and are
dying one after another.
The dmesg output looks like this:
[ 418.546245] sd 0:0:35:0: [sdai] tag#1756 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=7s

[ 420.524770] blk_update_request: critical medium error, dev sdai, sector 2048 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0
On the ZFS Ouutput I could see the disks starting with a few read errors and then advancing
to some 1000 of errors.
Seagate told me to put the drives in a windows or apple computer or otherwise they cannot help.
Anyone else having such Disk problems or am i the only one ?

Any ideas ?
