Dear xrootd-l, I'm seeing the issue that one of the disks on one of our xcache servers fills up disproportionally - that means it runs completely full until i get "no space left on device" errors without xcache running cleanup, while the other disks still have plenty of space left. My current df output: /dev/sdb btrfs 5,5T 5,2T 273G 96% /srv/xcache/b /dev/sda btrfs 5,5T 4,9T 584G 90% /srv/xcache/a /dev/sdh btrfs 5,5T 5,0T 562G 90% /srv/xcache/h /dev/sdj btrfs 5,5T 5,0T 551G 91% /srv/xcache/j /dev/sdf btrfs 5,5T 4,9T 579G 90% /srv/xcache/f [...] If you look at the first line you see that disk is 96% full while the others are around 90%. The issue occurred the first time after i built a new container for running xrootd. That change involved switching the container from centos7 to almalinux8 and changing the xrootd user id (ran chown and chgrp afterwards on the cache directories which are bind mounted). The xrootd version stayed the same (5.4.2). The high/low watermark configuration is the following: pfc.diskusage 0.90 0.95 I already tried clearing the misbehaving disk (after it ran full to 100%), but now the issue is reappearing. Has anyone seen similar issues or does it ring any bells for you? One thing i checked is the size that xrootd reports in the log for the total storage and that at least matches what i get when i sum the entries from `df`.
