Disks periodically unmounted in cloudlinux error

Once a week or month, one of my partitions gets unmounted. I am on a hetzner cloud server. I use cloudlinux and directadmin.

This is the state of the partitions when it fails:

[root@ns81 home3-81]# lsblk
NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda       8:0    0 228.9G  0 disk
├─sda1    8:1    0 228.8G  0 part /
├─sda14   8:14   0     1M  0 part
└─sda15   8:15   0    64M  0 part /boot/efi
sdb       8:16   0   500G  0 disk
sdc       8:32   0   500G  0 disk /home3-81
sdd       8:48   0   400G  0 disk /home4-81
sr0      11:0    1  1024M  0 rom

Missing partition: /home2-81

After running the disk mount command and to remount cagefs:

[root@ns81 home2-81]# lsblk
NAME    MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda       8:0    0 228.9G  0 disk
├─sda1    8:1    0 228.8G  0 part /
├─sda14   8:14   0     1M  0 part
└─sda15   8:15   0    64M  0 part /boot/efi
sdb       8:16   0   500G  0 disk /home2-81
sdc       8:32   0   500G  0 disk /home3-81
sdd       8:48   0   400G  0 disk /home4-81
sr0      11:0    1  1024M  0 rom

Everything works normally again.

Actual partition table:

UUID=252a70f2-2df2-4221-b5b9-3423197391e4                       /                       ext4    defaults,usrquota,grpquota      1 1
UUID=B824-9A11          /boot/efi               vfat    defaults,uid=0,gid=0,umask=077,shortname=winnt 0 2
/dev/disk/by-id/scsi-0HC_Volume_7036097 /home3-81 ext4 discard,nofail,defaults,usrquota,grpquota 0 0
/dev/disk/by-id/scsi-0HC_Volume_7036083 /home2-81 ext4 discard,nofail,defaults,usrquota,grpquota 0 0
/dev/disk/by-id/scsi-0HC_Volume_7044764 /home4-81 ext4 discard,nofail,defaults,usrquota,grpquota 0 0

Directadmin, Cloudlinux, Datacenter, all say that isn't a fault at his end.

What else could I check?

I appreciate any ideas or suggestions, thank you.

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.
