    Description

      There are increasing requirements to add lower than/greater than compare operator for the PCC rules:

      • File data that is larger than local disk capacity should not auto cache in PCC;
      • A range of UID/GID/ProjID could be auto cached on PCC;

      The following rule expressions are supported:

      lctl pcc add /mnt/lustre /mnt/pcc -p "projid=\{100}&size>\{1M}&size<\{500G} roid=5 ropcc=1"
lctl pcc add /mnt/lustre /mnt/pcc -p "projid>\{100}&projid<\{110} roid=5 ropcc=1"
lctl pcc add /mnt/lustre /mnt/pcc -p "uid<\{1500}&uid>\{1000} rwid=5"
