Clover Problems and Solutions

tluck · February 5, 2017

@sherlocks and other EmuVariable script testers:

Ok! I recoded the script once again and added a bit more status checking etc. Note: i finally had a failures similar to sherlocks - which helps in debugging.

And now I expect version will fix the failures to mount and find an ESP with Clover.

general aspects:

runs ok with Standard CloverDaemon or with LogoutHook

flow:

looks for all ESP partitions with CLOVER

it will re-use an existing already mounted ESP vs doing an unmount/mount

if the ESP is not mounted, first determine the fs type - versus using a trial and error approach to mount the ESP

finally if there are mounted ESPs with CLOVER, then remove any old /nvram.plist from the OS root.

and then write nvram.plist to all mounted ESP locations that have CLOVER

Note: attempts to gracefully unmount the ESP after use - but will not force an unmount.

attached is v1.10 80.save_nvram_plist.local. please test and report.

You did check failure case. Nice!!!. I will check your script and report.

Thank you so much

i think i understand what is happening. if you have an ESP mounted as a login user, when you shutdown, the logout process will start to unmount these filesystems. i will re-examine this some more!!!

syscl · February 5, 2017

Before report, my laptop smbios is no problem about model idefication.

thank you for hard work.

here is report

if DellSMBIOSPatch is no

스크린샷 2017-02-05 오후 9.45.38.png

if DellSMBIOSPatch is yes

스크린샷 2017-02-05 오후 9.47.13.png

Maybe all clover users use DellSMBIOSPatch yes if clover include this patch.

After test, now, returned clover r3998 with my fix.

Thank you

Hey @Sherlock, you are good, man!

Thanks for this important feedback that makes me realize I have to improve/fix some bugs in my code, here's the new source code

Clover 2.zip

Here's the compiled version

CLOVERX64.efi.zip

In new CLOVERX64.efi:

On your computer: no matter you check Dell SMBIOS Patch or uncheck Dell SMBIOS Patch, your Model Identifier should always be: MacBookPro13,3

The only difference is: Boot.log: Remap smbios table type 1 vs. Use origin smbios table type 1.

There's at least 6 possible cases I've tested on my XPS 13 9350(Iris 540):

No DellSMBIOSPatch key in config.plist, unchecked Dell SMBIOS Patch in binaries patching: truncate Model Identifier (as expected)
No DellSMBIOSPatch key in config.plist, checked Dell SMBIOS Patch in binaries patching: correct Model Identifier (as expected)
DellSMBIOSPatch = True, unchecked Dell SMBIOS Patch in binaries patching: truncate Model Identifier (as expected)
DellSMBIOSPatch = True, checked Dell SMBIOS Patch in binaries patching: correct Model Identifier (as expected)
DellSMBIOSPatch = False, unchecked Dell SMBIOS Patch in binaries patching: truncate Model Identifier (as expected)
DellSMBIOSPatch = False, checked Dell SMBIOS Patch in binaries patching: correct Model Identifier (as expected)

No more corrupt selection now.

Cheers,

@Sherlock, I have a question: why your EFI is always Resource busy? You mount your EFI when laptop startup? Normal case: this resource busy should not happen unless you operate on it.

Try to see which process read/write on your EFI.

Q.why your EFI is always Resource busy? You mount your EFI when laptop startup? Normal case: this resource busy should not happen unless you operate on it.

A.I am an ordinary user. i don't touch anything features. just boot, use itune, internet, etc. just to test clover bootloader, mount and put file in EFI.

tluck · February 5, 2017

if you have not turned off indexing for the ESP, meaning there is a .Spotlight-V100, then after writing nvram.plist, mdutil will lock it up for a short time.

look like i need to recoding to deal with logout doing unmounting of ESPs - the logout will unmount filesystems

So then it may be unmounted after we see it with a CLOVER before BUT before we write nvram.plist.

Thanks for clarification, but why Spotlight indexing on ESP? I don't see there's .Spotlight-V100 in my ESP partition.

There's another improvement can be considered to add:

If we mount ESP failed with information like: disk damage, then we can try to fsck the 'corrupted' ESP, then remount it. If we still fail to mount after fsck, then we dump NVRAM to root(/).

Wish this could help,

Fixed SMBIOS Model Identifier

DellSMBIOSPatch no

Model Identifier : no problem

DellSMBIOSPatch yes

Model Identifier : no problem

nice! thank you for hard work.

bronxteck · February 5, 2017

you can check spotlight status with mdutil -s /Volumes/EFI when EFI is mounted if it's not mounted it will return invalid path. to stop indexing it you can use mdutil -i off /Volumes/EFI when it is mounted. indexing EFI has corrupted EFI in the past for me on older OS's

syscl · February 5, 2017

@Sherlock

What's your result after executing mdutil -s /Volumes/EFI?

syscl

Sherlocks · February 5, 2017

@Sherlock

What's your result after executing mdutil -s /Volumes/EFI?

syscl

here

Supreme-MBP:~ supreme$ mdutil -s /Volumes/EFI

/Volumes/EFI:

Indexing enabled.

Supreme-MBP:~ supreme$

i have a question.

Should we manually turn off indexing, but when we switch to a new storage device?

Earlier rc scripts did not include this manual process.

Of course, there are a couple of things to consider when creating an nvram file with an ESP partition

syscl · February 5, 2017

here

Weird

syscls-MacBook:~ syscl$ ls /Volumes/EFI/
EFI		nvram.plist
syscls-MacBook:~ syscl$ mdutil -s /Volumes/EFI
/Volumes/EFI:
	Indexing enabled. 
syscls-MacBook:~ syscl$

But, I don't have resource busy and .Spotlight-V100.

syscl

bronxteck · February 5, 2017

sherlocks are you using an app to mount.

how are you mounting the volume syscl?

Sherlocks · February 5, 2017

syscls-MacBook:~ syscl$

But, I don't have resource busy and .Spotlight-V100.

syscl

i don't use other apps for ESP. my system is very clean. That is why I reported this situation when I failed.

when just use terminal for check script with no mount ESP, it's happen

Supreme-MBP:~ supreme$ sudo /etc/rc.shutdown.d/80.save_nvram_plist.local

Password:

Found ESP on disk0s1 with directory /Volumes/EFI/EFI/CLOVER

Saved current values to /Volumes/EFI/nvram.plist

Supreme-MBP:~ supreme$ umount(/Volumes/EFI): Resource busy -- try 'diskutil unmount'

bronxteck · February 5, 2017

so are you using clover NVRAM option to mount?

maybe you can test mdutil -i off /Volumes/EFI and see if script now works. on a real mac EFI is a protected Volume and it would never get indexed normally. it probably should never get indexed.

syscl · February 5, 2017

I use diskutil mount to mount my ESP.

I've written a script call mnt to mount ESP everytime I want. I don't use any other tools to mount my ESP.

mnt_and_umnt.zip

I just place it in /usr/sbin, then in terminal I can type mnt, then choose EFI to mount

syscl

Sherlocks · February 5, 2017

so are you using clover NVRAM option to mount?

i didn't touch any clover option. i like default. just install clover pkg.

add. syscl's mount script

Supreme-MBP:~ supreme$ mnt

After mounting disk0s1, how about now try to type in:

i wonder if the change in NVRAM.plist or the shutdown script triggers the spotlight to index causing it to become busy.
