I believe it's a fairly decent set up. Anyway recently I've had issues with my drives unmounting at will, and it's getting annoying. I'll come home from a dialysis session and everything is unmounted and lose what I had done on web site, or music I've been editing, for that I use Clementine. For the HTML editor I use BlueFish.
The drives mount right back up after going through the process, but what causes them to unmount on their own? I never turn off the computer..only reboot if required by an update. Any thoughts on this?.

The first screenshot shows my settings in Power management

The following two screenshots show settings in Screensaver

I do not think bluefish would affect the drive's mounting.

Check these first.

Is it only the main drive which Linux Mint 21.2 is installed on, that fails?....or are there external drives in the mix as well?

The mount options for my external (Found in Disks) looks like this.
Monut options are found via the little gear wheels immediately below the drive pic on the left hand side...

That particular drive is a true external, it resides on the desk beside the tower.
Be careful in the mount options...dont go click crazy.

It's ALL drives, whether it is the internal hard drive, external SSD drives, or USB sticks, it has no preference, they are all unmounted.
No big issues getting them back, just right click and mount.
It's only been doing it for 3 weeks, so that made me think it was maybe from an update. I do backups regularly, but wouldn't know how far to go back...or if drives were mounted or unmounted at that time.
Other than that little glitch, Linux works flawlessly, I've switched all 5 computers over, and glad I did.
I have a 76 year old sister that is in her Windows comfort zone (a contradiction of terms there) who refuses to even try my computers with Linux.

I'll try looking at the settings from your screen shots tomorrow, I have my sessions on Tuesday, Thursday and Saturday. 4 hours of sitting on my butt.


Thank You

The first thing that comes to mind is that so many drives will need a large power supply. For what looks like over 11TB over 11 drives, what power wattage is the power supply on the machine?

Less than 1000 watt PSU may not be advisable. Power blips can do odd things.

Are the power management settings set to do anything at all when the system is idle?

Are there any idle timeout settings? The one visible in Condobloke's post #2 shows:
"Suspend when inactive". It needs to be set to never to avoid unmounting.

It may be useful to fsck all the partitions to exclude errors on the filesystem from being implicated.
It may also be useful to check the health of the hard drives with the smartctl command from the smartmontools package.

Are there any "timeout=#" options in the /etc/fstab file? The timeout option can alter mounts to unmount after a period of time, though the default is to never unmount. Just some thoughts.

I’ve never known any disks to randomly unmount. Not unless it’s some kind of power saving feature or something?! I usually disable all power saving features and things like hibernation on my computers.

Whenever I’m not using my PC/laptop, I always save my work and shut it down. I don’t leave it on and unattended for any length of time.

Usually if there is a serious disk error, or if the power is interrupted (a surge, or a brief sudden drop in voltage), then sometimes disks will be unmounted and then remounted in read only mode. And if that happens and it’s NOT caused by a power related problem, it’s usually an indicator of a failing drive.

I’d echo @osprey ’s advice and fsck your partitions to check the file-systems are all intact and check the SMART information on each drive via smartctl.

Double checking fstab for timeouts is also a good shout!

I did just now switch to the never state for inactivity. And you may very well be on to something with the power supply. 5 of the 11 are actual hard drives with one of them being the internal that came with the PC, the others are USB Sticks.

This only started within the last month, other than that I've had no issues with Linux ever, it's an amazing system. I'll check everything when I get back from dialysis if they don't mess with me to bad. When they do I get so light headed I wouldn't remember my name..Then dialysis sucks.

Got back from dialysis and it's same stuff different day. I'll check Amazon and see if they have a better power supply, only thing that may put a wrench in the the machinery is that the computer is one notch up from small format...may not fit. If not I'll deal with the unmounting issue
