DRBD未输出cat /proc/drbd

Question

我同步我的新磁盘，drbdtop的输出：

Resource: myres: (Overall danger score: 14)
Local Disc(Primary):
volume 0 (/dev/drbd0): UpToDate(normal disk state)
volume 1 (/dev/drbd1): UpToDate(normal disk state)
volume 2 (/dev/drbd2): Inconsistent(data is not accessible or usable until resync is complete)

Connection to zfs.user.osdc2(Secondary): Connected(connected to zfs.user.osdc2)
volume 0: 
UpToDate(normal disk state)
volume 1:
UpToDate(normal disk state)
volume 2:
Replication:SyncTarget(local volume is being synchronized with data from zfs.user.osdc2) 95.6% remaining   UpToDate(normal disk state)  

但是cat /proc/drbd中没有关于我的资源的输出。只有：

version: 9.0.9-1 (api:2/proto:86-112)
GIT-hash: f7b979e7af01813e031aac579140237640c94569 build by mockbuild@, 2017-09-14 17:45:45
Transports (api:16): tcp (9.0.9-1)

为什么没有输出？我该如何解决这个问题呢？

/proc/drbd文件已在DRBD9.x版本中删除。相反，您应该使用drbdadm status来获取DRBD资源的当前状态。

如果您确实坚持旧的/proc/drbd输出，那么现在可以在sysfs中找到它。请注意，这仅限于每个连接。它位于：

/sys/kernel/debug/drbd/resources/${resource_name}/connections/${hostname}/0/proc_drbd
