Steps/procedure for Adding new disk to ACFS disk group or extending/increasing the size of ACFS file system diskgroup
Hello Guys, Here we are going to see the steps to add new disk to ACFS file system disk group or How to extend/increase the size of ACFS file system diskgroup (ACFS - Oracle Automatic Storage Management Cluster File System). This is also real time scenario of my environment. We received critical alert on ACFS file system mount point /prodtop which is having only 10GB free space and 90% of disk group space has been used. So customer requested us to increase size of /prodtop to another 10GB. Before extending the diskgroup [root@node1: ~]# df -Th /prodtop/ Filesystem Type Size Used Avail Use% Mounted on /dev/asm/prodtop-153 ACFS 95G 85G 11G 90% /prodtop So here we go. 1) Ask OS team to provide a new partitioned disk size of 10GB which should be shareable across all nodes if it is a clustered environment. For example *********** We got the below partitioned disk. Disk /dev/xvdj: 10.7 GB, 10737418240 bytes Device Boot
