Total Commander

Hi,
I know that is too soon to want something from Total Commander on Android N. But I only want to say, that system remount does not work, so is not possible to write to system, read works. My Nexus 5X is rooted with SuperSU 2.70, and when I try to remount system I get this error:

The error isn't specific to N. It means that there are open files on that volume which prevent the mount command from re-mounting the volume.

Thanks for your reply.

Here is log from CatLog app, maybe it will be more helpful

Well, it doesn't tell me anything new:

03-17 13:44:19.621 D/LightFlow:MainRunningService(nowJustAccessibility)( 3779): mount: '/dev/block/platform/soc.0/f9824900.sdhci/by-name/system'->'/system': Device or resource busy]

It also tells me that the partition has open files and cannot be remounted for that reason.

OK, thanks again. Will see if something will change in next (maybe in final) release of N.

Maybe it helps to reboot the system.

I tried it now, is same as before.

1. Could you try it with a button?
Command: su
Parameters: mount -o remount,rw /system
2. Could you try other apps with root support?

1. If this

is right, then it does not work

2. I found only one file manager which works with write function to system, Root Browser
https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree
Also I use Titanium Backup, f.lux, AdAway, Terminal Emulator, Flashify, FlashFire and Wakelock Detector with root rights.

I have downloaded and decompiled Root Browser. It uses mount too, but seems to call it with different parameters:
mount -o remount,rw /devicename /system

You need to check in the /proc/mounts file which device is mounted as /system, and then put this in "devicename".

OK
in mounts I found this: So I use which ends with same result as before:

Sorry, I really don't understand how Root Browser can remount a busy file system. I don't know enough of Linux to handle that. Therefore please use Root Browser instead of Total Commander for this operation, I cannot help you.

It's OK, thank you anyway.

Hello again
I talked with Chainfire (author of SuperSU) and he pointed me here:

and I tried command which works (also on Marshmallow)

Is it possible to use this command as default in your app (so I don't need to use custom button)?

That's odd, the order of the paramters (remount and rw) should not matter at all. Why would this give a "busy" error on Marshmallow? It makes no sense at all.

Is it possible to use this command as default in your app (so I don't need to use custom button)?

I will try it in beta 2. If you are on the beta channel, you should receive the beta automatically when it gets available.
