of the stackexchange post for example, my permissions and ownership on the sdcard folder /mnt/media_rw/UUID check out, but I can’t find any trace I did itįinally, I’m not smart enough to have figured out all this on my own, so it seems I was following some tutorial, but I can’t find it anymore. There could still be a step missing, but meanwhile this should allow to mount ext4 when you need it It has a bit of a gibberish name (using the UUID), but that’s all. My system auto-dectects the sd card, and mounts it everytime, even after reboot, updates, and so. I remember I still was in testing phase, and suddenly realising that it just all worked as I was expecting. I think I had observed it worked, then I unmounted it:Īnd then could just mount it in the system UIĪnd that seems to be all. (then it seems I went directly into the adb shell, no idea what I did and there’s no history It didn’t last more than 40 seconds, I think it wasn’t significant)Īdb shell mount -t ext4 -o rw,noatime /dev/block/mmcblk1p1 /mnt/media_rw/sdcard1 Yay, found it, for me it was “mmcblk1p1” then we want to turn it to ext4 ( this will erase everything on the card and ):
Searching for the sd card’s main partition (take it out, put it back in, and compare the outputs if you really need to be sure):

I think.ĮDIT: it seems I found what inspired me: external sd - Cyanogenmod - Filesystem for 64GB SD card, files larger than 4GB - Android Enthusiasts Stack Exchange The sd card was in the phone, with it’s classical fat32 partition, and unmouted. My fairphone 2 is under Lineage 17.1 and is rooted. I have a working ext4 sd card without disadvantages compared to fat32 (the system and all apps recognise it as expected), it seems that I forgot to document what I did, but my bash history has a good memory luckily. (I also read, that it has somehow a ROM and/or Kernel dependency → currently using LOS 17.1 / Android 10 on my FP2)ĮDIT: I edited a few things in the post, if you read this line for the first time just read the post again, look for the italic text
I tested this as well but it did not help me to solve this.īackground is that I cannot store files bigger than 4GB on the SD-card, but these files waste up too many space of my internal storage. I found some other threads where they talk about to modify the /vendor/etc/fstab.qcom. the ones you see in the subject), but as soon as I put it back in the phone it shows that there is an issue with the SD (“Tap here to fix”) and I asks me to format again.Ĭan I work around this “Tap here to fix” thing and just mount and use the SD as it is? So of course I’m able to format the SD on my laptop with any different filesystem I would like to have it (e.g. I was wondering if someone successfully format an SD-card for the FP2 with a filesystem different than FAT32 (the default and also the file system the phone will use when you put in the SD-card the first time).
