Hi,  
I have a load balancer, with three frontend servers (AWS EC2 Suse Linux), and because of our application requirements, I need all three systems to read and run the application from a single source. For this I have created a multi-attached EBS volume formatted in XFS.

The problem is that when restarting any of the three frontends, a corruption problem appears. Look at a part of the logs:

```auto
Jan 20 09:53:44 FRONT-2 kernel: XFS (nvme1n1p1): Metadata corruption detected at xfs_iread_extents+0x420/0x4f0 [xfs], >
Jan 20 09:53:44 FRONT-2 kernel: XFS (nvme1n1p1): Unmount and run xfs_repair
Jan 20 09:53:44 FRONT-2 kernel: XFS (nvme1n1p1): First 72 bytes of corrupted metadata buffer:

Jan 20 09:53:44 FRONT-2 kernel: 00000020: 00 00 00 04 00 00 4e 63 43 f4 45 43 2b 1a 43 7c ......NcC.EC+.C|

Jan 20 09:53:44 FRONT-2 kernel: 00000040: 0c 59 9a d7 00 00 00 00 .Y......

```

If I repair the filesystem, and we return to fill it with the application, it is a question of (little) time that it returns to appear this error again, although in another part of the disk. I have also tried to format them with ext4, and the problem keeps appearing.

This is my (identical) fstab file on all three servers:

```auto
LABEL=ROOT / xfs defaults 0 0
LABEL=EFI /boot/efi vfat defaults 0 0
LABEL=SCHOOLYARD /srv xfs defaults 0 0

```

I have also deleted an EBS, and created a new one just in case, but the problem persists.

Can you help me with this problem?

Thank you in advance,

---
