reformat whole sdcard as ext2/3/4

Hi,
There are a couple of threads asking this, but as far as I can see the problems are different on the DHD.
I use Linux pretty-much everywhere so have no need to read fat filesystems.
From what I can see by doing a mount, ext3 support is builtin
Code:
$mount | grep ext
/dev/block/mmcblk0p25 /system ext3 ro,relatime,errors=continue,data=ordered 0 0
/dev/block/mmcblk0p26 /data ext3 rw,nosuid,nodev,relatime,errors=continue,data=ordered 0 0
/dev/block/mmcblk0p27 /cache ext3 rw,nosuid,nodev,relatime,errors=continue,data=ordered 0 0
/dev/block/mmcblk0p28 /devlog ext3 rw,nosuid,nodev,relatime,errors=continue,data=ordered 0
So no custom kernel should be needed.
I tried re-creating the filesystem as ext3, but the phone wouldn't mount the partition. As there's no /etc/fstab in Android, I'm guessing the filesystems are listed somewhere else. Can anyone say where?
Second question: Journalling will write to the card more than I'd like, but I'm guessing ext3 or 4 with the journalling moved to the internal memory would be faster than ext2??
Anyone know of any drawbacks? What about ext4 support on the DHD, anyone know if it's there?

[Help] Tablet Bricked as storage may be full but I cannot mount sda1 in recovery

Hi,
I have an Iconia A501 with Tabooney 2.0 rom and booting with ClockworkMod Recovery 5.0
The story : I was unzipping a big file (backtrack img) using gunzip in the /sdcard/BT directory. A nothing was happening after 5 minutes and Ctrl+C did not work I tried to reboot and the tablet hangs at the "Iconia" splash screen.
As the file I tried to gunzip is very big I think that the local storage (that is not a sdcard but mounted in /sdcard) is full.
The recovery boot loader doesn't want to mount /sdcard
I can access to the tabled using adb in recovery mode but I cannont mount the local storage as in fstab it is described as /dev/sda1
Code:
cat /etc/fstab
/dev/block/mmcblk0p4 /cache ext4 rw
/dev/block/mmcblk0p8 /data ext4 rw
/dev/block/mmcblk0p3 /system ext4 rw
/dev/block/sda1 /sdcard vfat rw
/dev/block/mmcblk0p6 /flexrom ext4 rw
but I don't have any sda1 in /dev/block
Code:
ls /dev/block
loop0 loop3 loop6 mmcblk0p1 mmcblk0p4 mmcblk0p7
loop1 loop4 loop7 mmcblk0p2 mmcblk0p5 mmcblk0p8
loop2 loop5 mmcblk0 mmcblk0p3 mmcblk0p6 platform
I tried to mount all of the mmcblk devices but it doesn't work.
So I cannot mount it in order to clean the content.
Please if you have any Idea, tell me. I am also wondering if it is not a hardware failure as I think I should be able to see the device in /dev/block
Thanks

Well, as I missed time I did a factory reset and could boot again. I would have prefered not to loose data :-(.
Anyway if anybody knows a way to mount local storage partition in recovery I think it would be very usefull for many people as it seems it could happen to anybody.

[Q] Can we use EXT4 on our phones?

All the kernels support this, can we format /system, /data and everything else to ext4 and get more speed out of the file system on this phone and if so, how?

The official ROM with 2.6.35 kernel, is already using ext4 for /system /data and /cache partitions.
Code:
$ busybox mount|grep ext4
/dev/block/mmcblk0p12 on /system type ext4 (ro,relatime,barrier=1,nodelalloc,data=ordered)
/dev/block/mmcblk0p13 on /data type ext4 (rw,nosuid,nodev,relatime,barrier=1,nodelalloc,data=ordered,noauto_da_alloc)
/dev/block/mmcblk0p6 on /cache type ext4 (rw,nosuid,nodev,relatime,barrier=1,nodelalloc,data=ordered)

Maybe it is time to get over my fear of the 2.6.35 kernel with its atmel problems and its wifi reboots and update.

A500 dead internal SD card?

Hi guys, I'm a new poster but long time reader of these boards, which helped me a lot since I got my A500 and an Android phone years ago. So far I've always found a ready solution for my 'droid needs and wants here but this time I think I've hit a bricked (tablet) wall! :laugh::crying:
My A500 has Skrilax_CZ's bootloader v9 with CWM v6.0.4.5 on the secondary partition and for more than a year has been running HenrikE's Android 4.4.4 (OmniROM unofficial) from this thread: http://forum.xda-developers.com/showthread.php?t=2705989 The ROM has been going fine apart from a few random freezes but overall I like it.
Yesterday I was using the tablet to read a book and it started running Play store auto updates, I went to look at the store app to check which apps etc, then switched back to my book and the tablet froze. Normally I'd just long press the power button and then press it again to turn it on, so I did, only this time the ROM would not boot anymore and the tablet got stuck at the bootloader screen. I went into recovery and wiped cache and dalvik, no change. I went back to recovery and then I realized the partitions aren't mounting nor can be formatted! /system, /data, /cache, nothing:
E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p3
Without much hope I reinstalled the ROM with a data/factory reset and that of course didn't fix it. Tried to erase userdata and cache with fastboot, no change. It looks like either my internal SD card is broken/not found or my partitions are horribly corrupted? mmcblk0 isn't showing on /dev, see below from adb shell:
/dev/block # ls
loop0 loop2 loop4 loop6 mmcblk0p5 zram0
loop1 loop3 loop5 loop7 vold
/dev/block # fdisk /dev/block/mmcblk0
fdisk: can't open '/dev/block/mmcblk0'
/dev/block # parted
Error: No device found
Retry/Cancel? c
c
/dev/block #
/etc # cat fstab
/dev/block/mmcblk0p4 /cache ext4 rw
/dev/block/mmcblk0p8 /data ext4 rw
/dev/block/mmcblk0p3 /system ext4 rw
/etc # mount -t ext4 /dev/block/mmcblk0p8 /data
mount: mounting /dev/block/mmcblk0p8 on /data failed: No such file or directory
/etc #
Looking at other threads I guess the next step would be to try an APX reinstall however I use Linux and don't have a Windows machine around. While I can certainly spend my Easter break setting up a Windows Virtualbox :crying: do you guys think this is a hardware fault or something that can be fixed? Many thanks for any input. Oh and yeah I do have the tablet's SBK number.

I forgot to paste this:

Hi all, I've narrowed it down to a bad sector on the tablet's internal storage and posted on this older thread about the same problem http://forum.xda-developers.com/showthread.php?t=1691729&page=5

i-tec USBOTG device with HDMI and storage devices (SCSI HDD/SSD, SDcard, USB-3 + USB-C connector)

Hi everybody,
I am looking for ways to mount storage devices with more than one partitions via usbotg and my i-tec 'docking station'.
That worked on my old MOTO G5 on LINEAGEOS17.1 with an USB Stick for vfat and ext4 partitions out of the box, but the luks partitions were not mounted.
WIth my LGV20 and LINEAGEOS18.1 only the first partitions are showing up. The 2nd and 3rd partition are not mounted.
-> I would like to mount an USB Stick with vfat, ext4 (boot) and a luks partition.
-> I would like to mount an HDD with a vfat and luks partition
I somehow feel and know that this should be an easy task, if you know how to mount partitions in android.
I am thinking about trying to mount the partitions in the TWRP terminal and then copy the command in /fstab.elsa
/fstab.elsa content:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
#TODO: Add 'check' as fs_mgr_flags with data partition.
# Currently we dont have e2fsck compiled. So fs check would failed.

For the terminal mount /dev/sda1 didn't work.
Any ideas how I have to adress the USB device?
