acfsutil registry concurrency issue
Date: Wed, 8 Dec 2021 13:53:30 +0000
Message-ID: <1b880bbdfc1244029dfe3eddd712fa90_at_vontobel.com>
We hit a concurrency issue with acfsutil registry.
The following commands delete the ACFS and its underpinning volume:
2021-12-07 14:35:53,360 DEBUG > exec_os starting: sudo /usr/sbin/acfsutil registry -d /dev/asm/XXXX41c_1-192 2021-12-07 14:35:53,814 DEBUG > exec_os ended: exec_os:command: sudo /usr/sbin/acfsutil registry -d /dev/asm/XXXX41c_1-192 acfsutil registry: successfully removed ACFS volume /dev/asm/XXXX41c_1-192 from Oracle Registry
2021-12-07 14:35:53,817 DEBUG > exec_os starting: /u00/oracle/GI/product/21.3.0/bin/srvctl stop volume -force -diskgroup DATA -volume XXXX41C_1 2021-12-07 14:35:55,019 DEBUG > exec_os ended: exec_os:command: /u00/oracle/GI/product/21.3.0/bin/srvctl stop volume -force -diskgroup DATA -volume XXXX41C_1
2021-12-07 14:35:55,021 DEBUG > exec_os starting: /u00/oracle/GI/product/21.3.0/bin/asmcmd voldelete -G DATA XXXX41C_1 2021-12-07 14:35:57,519 DEBUG > exec_os ended: exec_os:command: /u00/oracle/GI/product/21.3.0/bin/asmcmd voldelete -G DATA XXXX41C_1
The following acfsutil register -a (add) command executed concurrently by another process fails because of the deleted volume, even though it's trying to add a completely different volume.
2021-12-07 14:35:51,878 DEBUG > exec_os starting: sudo /usr/sbin/acfsutil registry -a -n all -u oracle /dev/asm/YYYY42cp2_1-192 /u00/oracle/oradata01/YYYY42C/YYYY42CP2 2021-12-07 14:35:58,664 DEBUG > exec_os ended: exec_os:command: sudo /usr/sbin/acfsutil registry -a -n all -u oracle /dev/asm/YYYY42cp2_1-192 /u00/oracle/oradata01/YYYY42C/YYYY42CP2 exec_os:std_err: acfsutil registry: ACFS-09173: The srvctl command line "/u00/oracle/GI/product/21.3.0/bin/srvctl add filesystem -device /dev/asm/YYYY42cp2_1-192 -path /u00/oracle/oradata01/YYYY42C/YYYY42CP2 -user oracle" failed to execute. (0) acfsutil registry: ACFS-03111: unable to add ACFS mount /u00/oracle/oradata01/YYYY42C/YYYY42CP2 within Oracle Registry
PRCT-1520 : ASM volume device /dev/asm/XXXX41c_1-192 does not exist.
Is there an Oracle native way to overcome this?
We'd like to avoid the serialization with a self-developed wrapper.
Best regards,
Nenad
