Last updated on AUGUST 02, 2018

Applies to:

Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.11 [Release 11.0]
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on SPARC (32-bit)
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on x86 (32-bit)

Symptoms

1) Solaris Volume Manager (SVM) commands, metastat and metadevadm, hang or do not complete.

Running truss on the hanging metadevadm command:

# truss -aefdD -vall -wall -rall -ua.out -o /var/tmp/metadevadm-l-r.truss.out metadevadm -l -r

Shows that the hang occurs in the open() system call on file "/dev/.devlink_db".

Here is an abbreviated output from truss showing the point where the open() system call was hanging and then broken with a <ctrl>-C signal.

 The SVM SMF service "system/mdmonitor:default" executes the "metadevadm -l -r" command, which is shown to hang in symptom 1 above.
