Description Barry Jackson 2015-04-05 01:00:54 CEST

Description of problem:
Installed RC to an external gpt USB hard drive in EFI mode, using classic KDE DVD iso on a USB stick (created for UEFI by isodumper)

Current cauldron media also enabled plus efibootmgr from updates_testing in another local repo.

Install went fine and system rebooted without problem.
However on further testing I notice that the ESP is not mounted in the running system, despite it being in fstab.
grub2-install fails with error reporting it can't find ESP.
Mounting the ESP manually fixes this.

fstab: (The ESP is commented as"# Entry for /dev/sdj1 :"

# Entry for /dev/sdi5 :

However there is also an fstab.old:

# Entry for /dev/sdi5 :

# Entry for /dev/sdj1 :

none /proc proc defaults 0 0
# Entry for /dev/sdb5 :

# Entry for /dev/sdi6 :
UUID=bf663611-062d-4482-b2a8-20656dfa9979 swap swap defaults,nofail 0 0

The only difference is that the umask on the ESP was changed 14 minutes after the initial file creation on first reboot I guess.
No idea yet if this is affecting anything - just observations.

Priority: Normal => release_blocker

Bah! It's late! Sorry. The ESP is UUID=F4C3-3A1B /boot/EFI obviously.

/OT
The other vfat entry (UUID=9154-7FF4 /mnt/hd vfat) is the USB stick used for the install - not sure why that would be in fstab.

Comment 4 Barry Jackson 2015-04-05 02:09:23 CEST

Changing the fstab entry from:
UUID=F4C3-3A1B /boot/EFI vfat umask=000,users,iocharset=utf8,exec,noauto,nofail 0 0
to:
UUID=F4C3-3A1B /boot/EFI vfat umask=000,iocharset=utf8 0 0
Does mount the ESP on boot

I'm not suggesting that this would be correct in this case, just testing that it works (the replacement line was pulled from a working fstab I have in a VM).

Comment 5 Barry Jackson 2015-04-05 10:38:42 CEST

Dropping priority as I now realize that this is more of a corner case, since 99% of systems would have a normally mounted ESP on a non-removable drive.

I have no other UEFI systems on this machine as it has a dual BIOS, so Mageia has put the ESP on the USB drive.

However, I think this should still work, and provision should be provided so it does.

Many people switching from legacy BIOS to UEFI will want to make test installations on a removable drive before committing to a full change over, so this situation can arise.

Priority: release_blocker => High
Summary: ESP not mounted in running system => ESP not mounted in running system, when Mageia is the only EFI system on external HD (hybrid BIOS)
