[SOLVED]fstab entries ignored after boot

Seems that the entries for partitions I've set to automount are ignored or something else remounts them with different options. I've checked my fstab and I have no errors. Also I'm using those mounts for many years and recently I have problems with several partitions and I found that this is the problem. What changed and this started to happens?
I found about this recently because I had problems with scripts which didn't run from several partitions and I found that those partitions have been mounted with different options included noexec while I have specified exec option for those on fstab.

Re: [SOLVED]fstab entries ignored after boot

Don't copy and paste out of the pager, i truncates lines
The findmnt output is clearly cut off and ends in a single "s" what might hint at some subvolume being mounted there - or whatever else.
What happens if you just comment gamedisk4 and gamedisk3 (the two spurious noexec mounts)?
Are they still mounted automagically?

Re: [SOLVED]fstab entries ignored after boot

@seth sorry about that, but I don't think that matters in my case because I don't use/have subvolumes, or other special futures of btrfs. I just use it as alternative to ntfs because it works fine on windows(which I barely use, but I need them for test sometimes).
If I comment out the lines of those partitions, they don't automount on reboot. Then, when I revert the change to normal in fstab, run daemon-reload and mount them with "mount -all", again system mounts them with as before and ignore my options.
@scimmia, tree gives command not found. Is on some not basic package which I need to install?

Re: [SOLVED]fstab entries ignored after boot

The point is not the subvolume specifically but that we're missing data on the concerned mounts because of the truncation.

If I comment out the lines of those partitions, they don't automount on reboot.

One thing that sticks out is that the fstab entry for gamedisk3 is wrong (the "00" at the end needs some space between them) but whether that causes the fstab generator to apply wild defaults, idk.

No, it's not 00, the editor here ate the space(I don't know why on that specific line, but I just re-checked it).

* the noexec isn't there for some because I remounted them with "exec" after the reboot.

Re: [SOLVED]fstab entries ignored after boot

Ok, on a close look it must be the option order.
Put "exec" behind "user".

Re: [SOLVED]fstab entries ignored after boot

You found it!! Yes that was the problem. I initially didn't have exec for those partitions and I didn't know that order matters in options. But seems that it does. Thank you.
