+++ This bug was initially created as a clone of Bug #1355706 +++ +++ This bug was initially created as a clone of Bug #1342459 +++ Description of problem: ======================= If we have sticky bit files present in a distribute replicate volume, then they get displayed as 'skipped' in the scrub status output. Considering that the actual file would have anyways gotten considered, the scrubber should ideally be ignoring all T files. Version-Release number of selected component (if applicable): ========================================================== How reproducible: ================ Reporting the first occurrence. Steps to Reproduce: =================== 1. Have a 4node cluster, with n*2 distribute replicate volume. 2. Create files from the mountpoint 3. Create a scenario such that sticky bit files are created (say, kill a brick process, and do creates) 4. Validate the scrub status output Actual results: ================ Step4 shows a number>0 in the field 'Files skipped' in scrub status output. Expected results: ================== Step4 should not show any files as skipped, as there is no open FD while the scrubber is doing its run.
