The result is that very few dirty buffers are recorded, but the rsync that usually takes a few seconds, now stops for minutes at a time. The machine also stutters, for example as I open a snall file on /data1. The following perf run is of the rsync. $ sudo sysctl vm.drop_caches=3D3 $ sudo mount -o remount,nodelalloc /data1 $ (d=3D"`date`" ; sudo rsync -aHSK --stats --progress --checksum-choice=3Dn= one --no-compress -W /data2/no-backup/old-backups/tapes/13/file.1.data /data1/no-backup/old-backups/tapes-again/13/ ; echo "`date`: started $d") $ sudo perf record -p 1531839 -g sleep 60 $ sudo perf report --no-children --stdio -i perf.data I will add the logs as an attachment (I hope). --=20 You may reply to this email to add a comment.
