[LU-12516] volatile file creation in .lustre/fid/

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.3
• Assignee: Alex Zhuravlev

Description

this is needed to allow striping manipulation using FID.
for example, for commands like lfs mirror create /mnt/lustre/.lustre/fid/[0x20000401:0x1:0x0]
this is, in turn, is useful for utilities like automatic file replication which takes FIDs from LiPE and can save on fid2path and subsequent path traversal (number of sync RPCs)
