Systemd 228 introduced a global task limit of 512 for system services. System 231 changed this to 15% of pid_max, or 4915. In particular the one of systemd 228 is too low for multipathd with many LUNs. Use TasksMax=infinity to overcome this limitation. --- multipathd/multipathd.service | 1 + 1 file changed, 1 insertion(+) diff --git a/multipathd/multipathd.service b/multipathd/multipathd.service index 0cf99b2f2df5..ba24983ef291 100644 --- a/multipathd/multipathd.service +++ b/multipathd/multipathd.service @@ -16,6 +16,7 @@ LimitCORE=infinity ExecStartPre=-/sbin/modprobe -a scsi_dh_alua scsi_dh_emc scsi_dh_rdac dm-multipath ExecStart=/sbin/multipathd -d -s ExecReload=/sbin/multipathd reconfigure +TasksMax=infinity [Install] WantedBy=sysinit.target -- 2.15.1 -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
