Hello,

I am a Ph.D student at UNCC and our team is working on the Lustre filesystem. I am reading extended attributes of the ldiskfs for every inode. I have used this source https://wiki.lustre.org/PFL2_High_Level_Design to interpret the layout in which the extended attributes are stored. 

For the Lustre image we are using, there are 605 inodes out of which 253 have extended attributes. The count of lma is also 253, which is correct. However the only 22 inodes seem to have linkEA attributes and 2 inodes have lovEA attributes. The count for linkEA and lovEA is seems to be really small compared to the count for lma.

I am wondering if there is an updated document on the layout of extended attributes for the ldiskfs inodes.

Thanks and regards
