From f3bc4ccc2edf5ad2a99d6ba2795b9999fe76c3df Mon Sep 17 00:00:00 2001 From: bgbhpe Date: Fri, 8 Jul 2016 11:43:56 -0400 Subject: rules: block: add support for pmem devices (#3683) Persistent memory devices can be exposed as block devices as /dev/pmemN and /dev/pmemNs. pmemN is the raw device and is byte-addressable from within the kernel and when mmapped by applications from a DAX-mounted file system. pmemNs has the block translation table (BTT) layered on top, offering atomic sector/block access. Both pmemN and pmemNs are expected to contain file systems. blkid(8) and lsblk(8) seem to correctly report on pmemN and pmemNs. systemd v219 will populate /dev/disk/by-uuid/ when, for example, mkfs is used on pmem, but systemd v228 does not. Add pmem to the whitelist. --- rules/60-block.rules | 2 +- rules/60-persistent-storage.rules | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'rules') diff --git a/rules/60-block.rules b/rules/60-block.rules index c74caca49f..42c75974a5 100644 --- a/rules/60-block.rules +++ b/rules/60-block.rules @@ -8,4 +8,4 @@ ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_ ACTION=="change", SUBSYSTEM=="scsi", ENV{DEVTYPE}=="scsi_device", TEST=="block", ATTR{block/*/uevent}="change" # watch metadata changes, caused by tools closing the device node which was opened for writing -ACTION!="remove", SUBSYSTEM=="block", KERNEL=="loop*|nvme*|sd*|vd*|xvd*", OPTIONS+="watch" +ACTION!="remove", SUBSYSTEM=="block", KERNEL=="loop*|nvme*|sd*|vd*|xvd*|pmem*", OPTIONS+="watch" diff --git a/rules/60-persistent-storage.rules b/rules/60-persistent-storage.rules index cbd44cb242..dbf10b286f 100644 --- a/rules/60-persistent-storage.rules +++ b/rules/60-persistent-storage.rules @@ -6,7 +6,7 @@ ACTION=="remove", GOTO="persistent_storage_end" SUBSYSTEM!="block", GOTO="persistent_storage_end" -KERNEL!="loop*|mmcblk*[0-9]|msblk*[0-9]|mspblk*[0-9]|nvme*|sd*|sr*|vd*|xvd*|bcache*|cciss*|dasd*|ubd*|scm*", GOTO="persistent_storage_end" +KERNEL!="loop*|mmcblk*[0-9]|msblk*[0-9]|mspblk*[0-9]|nvme*|sd*|sr*|vd*|xvd*|bcache*|cciss*|dasd*|ubd*|scm*|pmem*", GOTO="persistent_storage_end" # ignore partitions that span the entire disk TEST=="whole_disk", GOTO="persistent_storage_end" -- cgit v1.2.3-54-g00ecf
