[QUESTION] Too much time to delete file on xfs filesystem

[Ryan Lee <ryanlee.lahk@xxxxxxxxx>]

Hi, My name is Ryan.

 Nowadays, Our company product has a new problem which is taking too much time to delete file on xfs filesystem.

 When I try to delete the file (18GByte, It was just one file), it would take around 7 minutes 30 seconds.

I've known like this, the XFS filesystem's deleting time is less than other filesystems such as EXT3, EXT4 and reiserFS.

 

 What I did here.

-rw-r--r--   1 root     root     18924699648 Jan  2  1971 hdd_write_test6.ts

# time rm hdd_write_test6.ts

 

real    7m 28.10s

user    0m 0.00s

sys     0m 9.79s

#

 Again, I have an opinion about XFS.

XFS is faster than other filesystem as I told you. and I've got this information from internet.

But, the test result makes me confusing about that I've belived about XFS filesystem.

 

Am I right??

 So, Please, give me any information about this what you have.

 

Our product use this version like below.

kernel  2.6.37

xfsprogs 3.1.7

  

Thanks, Ryan.
