No problem shutting it down for a short time. As long as you have registered a changelog reader, Lustre will retain the logs until Robinhood reads and acknowledge the record.It may be problematic if this situation stays for a very long time: changelogs will accumulate on the MDT until space is missing. In this case if may not be possible to create files on the MDT, or the MDS may decide to drop the log records.So it is worth monitoring the number of pending log records on the mdt. Information should be available in a /proc or /sys (I don't have it in mind right now).RegardsThomas -------- Message d'origine --------De : Russell Jones <[email protected]> Date : 27/07/2023 18:04 (GMT+01:00) À : [email protected] Objet : [robinhood-support] Historical changelog reading? Hi all,Quick question on how Robinhood handles being offline - If changelogs are enabled on the MDT's, and the Robinhood service is offline for a short period of time, when it's turned back on is Robinhood able to pick up where it left off and read historical changelogs from the MDT's (is this a thing?)? Or would I need to do another filesystem scan to have it pick up what it missed?
