Solution:
do ps -ef|grep crsd.bin and then kill -9 the same
process id at OS level, this process after a kill will be respawn automatically
and crs hangs will get resolved.
Eg.
$ ps -ef|grep crsd.bin
root 6029 4284 0 Jan22 ? 03:00:47 /home/oracle/product/crs/bin/crsd.bin reboot
oracle 4454 27612 0 14:25 pts/1 00:00:00 grep crsd.bin
As root,
# kill -9 6029
exit
$ ps -ef|grep crsd.bin
This will show new process id and crs_stat -t ; will work now.
Eg.
$ ps -ef|grep crsd.bin
root 6029 4284 0 Jan22 ? 03:00:47 /home/oracle/product/crs/bin/crsd.bin reboot
oracle 4454 27612 0 14:25 pts/1 00:00:00 grep crsd.bin
As root,
# kill -9 6029
exit
$ ps -ef|grep crsd.bin
This will show new process id and crs_stat -t ; will work now.
The crsd.log is full of errors like shown below:
category: 1234, operation: scls_process_join, loc: childcrash, OS error: 0, other: Abnormal termination of the child
..
category: 1234, operation: scls_process_spawn, loc: read_pipe, OS error: 12, other: EOF on read pipe
--
This messages can happen if crsd.bin is hung or OS level failure caused all problems in crsd
--
Please check OS log with help from OS sysadmin to see if there are any obvious issues.
--
To avoid hitting known bugs in CRS we recommend you apply latest CRS PSU#2 Bundle patch (#9207257) available.
