Remount shared folder: alternative to mount -a
Some shared folders unexpectedly get unmounted sometimes, therefore I've scheduled a mount -a with the purpose of remountig only those shared folders that got unmounted in the meantime.
In the manual, however, I read:
Note that it is a bad practice to use mount -a for fstab checking.
The recommended solution is findmnt --verify.
It is my understanding that findmnt --verify checks all mounted filesystems, and does not perform any further action. I would like to only check cifs mounts and remount them if any error is encountered.
What is the preferred way to accomplish this?
Edit:
Thanks to Soren A for pointing out how to filter only cifs filesystems: findmnt -t cifs --verify.
Update:
I added a line in my /etc/fstab and findmnt --verify did not detect it as being unmounted. It thus seems ineffective at detecting unmounted entries in /etc/fstab. Maybe I just mistook fstab checking for checking whether all entries in fstab are correctly mounted instead of just verify /etc/fstab parsability and usability.

It seems I have misunderstood the meaning of the mount manual:
it is a bad practice to use mount -a for fstab checking.
Maybe because this is what I was looking for, I took it to mean: checking whether all entries in fstab are correctly mounted.
Instead, the findmnt manual says:
-x, --verify
Check mount table content. The default is to verify /etc/fstab parsability and usability.
So, it seems findmnt --verify is just meant to check the correctness of /etc/fstab, regardless of the current state of mounted filesystems.
