Hi,
Please forget my first question, I made a mistake.
For " the recent lustre versions use a 1KB inode size by default and the
default format options create 1 inodes for every 2.5 KB of MDT space" :
I checked the inode size is 1KB and in my online systems, as you said ,
about 40~41% of mdt
Thanks a lot.
I have two more questions:
1) Assume I consider the mdt space use the method described in lustre
manual, by calculation, the metadata space is 400GB.
After format(default option), about 160GB(40% of 400GB) preallocated for
inodes, so the avalaible inodes number is less than

Hello, I have some question about metadata space.
1) I have ten 960GB SAS SSDs for mdt,after done raid10,we have 4.7TB space free.
after formated as mdt,we only have 2.6TB space free; so where the
2.1TB space go ?
2) for the 2.6TB space, what's it used for?
