Lets assume we already have functional disk group name sybase and we need to create /export/home/sybase of 200 GB.Environment is Solaris and VxVM .Considering the fact that existing disk group have more than 200 GB free space.
So we know that disk group is having space to provision new file system.Lets go through procedure how to create a veritas file system in solaris to be followed .
1.Validate the available free space in disk group.You can use below command to get required information. # vxassist -g sybase maxsize This command will display free space in disk group sybase in MB.Divide result by 1024 and get available space in disk group. 2. Create a Veritas Volume in disk group of 200 GB # vxassist -g sybase -U fsgen make sybvol 200g Above command will create a volume name sybvol of 200 GB. 3. Create a File System on new volume # mkfs -F vxfs -o largefiles /dev/vx/rdsk/sybase/sybvol This command will layout file system with large files support. 4. Create Mount Point and update vfstab for it to remain consistent across reboot. # mkdir /export/home/sybase # chmod 755 /export/home/sybase # chown sybase:sybase /export/home/sybase 5. Mount FS You can mount simply typing mountall or manual mount command .See below for detail. # mountall OR # mount -F vxfs /dev/vx/dsk/sybase/sybvol /export/home/sybase 6.
