Presist partition question



Description

Dear Qualcomm
We checked the presist file system. The file system shows presist used 108K but we checked the free space only has 788K(We think It should around 4M-108K). Do you know who use the other space in presist?

busybox du -h
48.0K ./qcom/softap
52.0K ./qcom
4.0K ./usf/epos
8.0K ./usf
108.0K .
root@android:/persist # df
df
Filesystem Size Used Free Blksize
/dev 388M 64K 388M 4096
/mnt/asec 388M 0K 388M 4096
/mnt/obb 388M 0K 388M 4096
/system 504M 248M 255M 4096
/data 1009M 66M 942M 4096
/cache 31M 4M 27M 4096
/persist 4M 4M 788K 4096
/firmware 63M 45M 18M 16384
/storage/sdcard0 1009M 66M 942M 4096

Yours Sincerely

Hi,

Yes, as the file is deleted it falls under garbage data now and can be cleaned or replaced.
You can refer to the below link it throws more light on this:

Thanks.

Hi
Thanks for your respond. We need to confirm with you one more thing.
Is the data which doesn't have file name garbage data? And we can clean them or replace them by other file.

Yours Sincerely
Fred Yu

Hi,

I checked the issue on our device and observed similar results. df command is showing more disk space usage compared to df command. On my setup I got the below results:

>>
/data/busybox/busybox du -h /persist
12.0k /persist

>>
/data/busybox/busybox df -h /persist
Filesystem Size Used Available Use% Mounted on
/dev/block/platform/msm_sdcc.3/by-num/p14
9.9M 4.1M 5.8M 41% /persist

Please find the explanation for the same below:
When you delete a file that is being held "open" by a process what actually happens is the file's name is deleted but not its inode (and its data). df sees what is happening at filesystem level whereas du sees what is happening at file/directory level. If the filename is gone du doesn't see it in the directory any longer. However since the inode is still in use df sees that the filesystem is still using the space. Hope this answers your question.

Thanks,
Vijitha
