Database Develop

[WM5] just another tweak

Try to add new DWORD value:
HKEY_LOCAL_MACHINE\System\StorageManager\FATFS
BufferSize=0x900 [that is 2304 decimal]
[add BufferSize, wait 30 seconds and reboot ]
Use value between 0x800 and 0xA00.
If buffer size is not defined default value is 0x20 [==32].
SPB benchmark told me, that some file operations could be faster:
Code:
Write 1MB file 0,39%
Read 1MB file 5,04%
Copy 1MB file -1,31%
Write 10KB x 100 files 12,23%
Read 10KB x 100 files 22,31%
Copy 10KB x 100 files 8,44%
Directory list of 2000 files 38,05%
Internal database read 2,50%
Don't use BufferSize>0xA00 - results are not so good [due to buffer management overhead].
BufferSize<0x800 - results are not so good, too.
BTW. Increasing CacheSize above 0x1000 [decimal 4096] doesn't increase file system performance.

[Q] Size of /store/media/ of a 16GB TP

I have a 16gb touchpad, and have only webos and CM9 installed. My sdcard's capacity is about 6.9GBs.
How much is yours? Because i think im missing few gigabytes.
on lvm,
with pvscan i can see a physical partition of about 14GB and with lvscan i can see a sum of about 10GB of logical partitions. If i run the command lvresize -L +90000M /store/media it wont increase it at all

Don't forget that WebOS has a set of other partitions it needs as well - /boot, the swap, the mojodb, update room, etc. A fresh install of WebOS from factory leaves yo with about 14 or so gigs of room on /media/card. Then, when you install CM9, it shrinks that down further by about another almost-2.
Don't forget, you also might have a few apps that have installed themselves to the SD Card, as well as nandroid backups, new flash able zips, ,movies / music / pictures etc from either of the two OS's. They share the SD card partition between them.
Hope it helps.

Yes but that shouldn't reduce the total space of the media partition but the free space :/

The stuff that's installed on there will lower the free space. The actual partition size is changed by installing any form of Android / Linux / anything except the actual WebOS.
What explorer are you using that shows it's only 7 GB in size ? Root Explorer shows that my SD Card has 3.75 used, 6.88 free (so 10.63 total). I have the 16GB Touchpad with just yesterday's official nightly installed. I connected my tablet while booted into WebOS, and by using lvm.static lvdisplay (and saving the result to a text file) I get the following:

So, boot up, run Novaterm, and issue the lvm.static command and read what it shows you for your /media/card partition. And check for anything that isn't in the list I just posted.

but not sure how to fix it

What I would do, if I were you, would be to do a nandroid backup of anything you value, then factory restore your touchpad like THIS THREAD tells you. It'll then allow you to get your partitions back the way they should be. And will give you your 10GB /media/card once you install CM9 again to it.

[Q] Bricked or not bricked? That is the question!

I got one of those original HP 16GB WIFI TouchPad. I had the famous too-discharged-won't-boot-anymore ( question-mark-battery-logo issue ) 3 times which I managed to resolve through usage of this forum ( Thank you! ) This time, I don't know what to do. Nothing on screen at all, I can only 'see' something through looking at what device the TouchPad appears as on the USB port:

The other mode I can start the TouchPad in is the 'QHSUSB_DLOAD'

Taken from @jcsullins toolbox script, with the TouchPad booted in 'Palm' mode I can enter a few commands and eventually able to establish a SSH connection with my TouchPad.

That great! Now what?
Is my TouchPad really dead?
Can I use it still for Android?
How can I reflash or put back 'Web OS Recovery' ?
With all of the access I feel I have, do I need 'WebOS Recovery' at all?
Can't I just 'DD' one or more of the 14 partitions ?

Try to (just) load this version of moboot-dfu instead:
https://goo.im/devs/jcsullins/tpdebrick/moboot-dfu-20150128
Do you see small text appear on the screen after loading it?
If so, are there two lines with "a6_test"? If so, what do they say. If not, what does it say on the screen.
If nothing appears on screen, does it show up when you run "fastboot devices" ?
If so, does it allow you to run "fastboot oem klogs 2>&1"? If so, upload the output and give link here.

building errors due to java Xxm

Hello,
When I try to build my ROM, I keep getting this error, despite setting Xxm to 2 gb. Does this need to be at least 4gb?
I'm running Kubuntu 16.04 on a 4gb ram system. Would it be safe to set it to 4gb while only running 4gb of ram (plus 3gb swap on usb)
Also, please see my original post here for more info:

Can anyone help me to find partition by-name lists on OnePlus 3t? I have also tried Diskinfo to find the details but it didn't helped me. I have also followed this https://forum.xda-developers.com/t/guide-internal-memory-data-deleted-files-recovery.3093292/ but it's getting hard for me to get into the b-name partition list of my device.
Or do you guys know any other alternatives on how to make an image of OnePlus internal storage to PC?
I'm stucked since days. Please need some help.

is there any genius who can help me on this matter?

Have a look at both of these commands:
Bash:
cat /proc/partitions
ls -l /dev/block/bootdevice/by-name

Lol! The command is lower case L - ls. Not 1 - 1s.
