Examine the output of this command:
ASMCMD> volinfo –G ACFS -a
Diskgroup Name: ACFS
Volume Name: VOL1
Volume Device: /dev/asm/vol1-280
State: ENABLED
Size (MB): 248
Resize Unit (MB): 32
Redundancy: MIRROR
Stripe Columns: 4
Stripe Width (K): 128
Usage: ACFS
Mountpath: /u01/app/grid/acfsmount
The ACFS disk group is a normal redundancy disk group with 5 GB of free space.
To increase the size of the ACFS file system, you execute this command as the root user:
$ /sbin/acfsutil size +200M /u01/app/grid/acfsmount
Which two statements are true regarding the outcome of this command?
A.
It resizes VOL1.
B.
It fails to resize the filesystem because it must be unmounted before resizing.
C.
It fails to resize VOL1 because it must be executed as a user belonging to the SYSASM group.
D.
It succeeds but leaves the filesystem unmounted.
E.
It resizes the filesystem mounted on /u01/app/grid/acfsmount.
Explanation:
Hello
Correct answers should be A and E.
D is incorrect, resize will not unmount the filesystem.
Hello
Yes I agree with you. Correct answer should be A and E
Regards
I agree A and E
The correct is A & D:
Oracle ACFS file systems can be “dynamically resized” to accommodate additional file and snapshot storage requirements.
…
Oracle ADVM volumes may be created on demand from Oracle ASM disk group storage and “dynamically resized as required”.
https://docs.oracle.com/cd/E18283_01/server.112/e16102/asmfilesystem.htm#CACHFACJ
acfsutil size grows or shrinks the mounted Oracle ACFS and its underlying Oracle ADVM storage to match the new size specified. This operation also resizes the underlying Oracle ASM Volume file to match the new length that is specified.
https://docs.oracle.com/cd/E18283_01/server.112/e16102/asmfs_util010.htm#CACBACBA
An ACES file system can be resized, and it will automatically resize the volume if there is sufficient space in the disk group. The images file system is near capacity. Increase the file system by 128 MB. As the root user, use the acfsutil size +128M /u01/app/oracle/acfsmount/images command.
[root@host01]# acfsutil size +128M /u01/app/oracle/acfsmount/images
acfsutil size: new file system size: 671088640 (640MB)
Ops! A & E
https://docs.oracle.com/cd/E18283_01/server.112/e16102/asmfilesystem.htm#CACCIDEE
In addition to sharing file data, Oracle ACFS provides additional storage management services including support for the Oracle Restart mount registry and the Oracle Grid Infrastructure clusterwide mount registry, dynamic on-line file system resizing, and multiple space-efficient snapshots for each file system
A,E is correct.
