Support for a multiterabyte UFS file system assumes the availability of multiterabyte LUNs, provided as Solaris Volume Manager or VxVM volumes, or as physical disks greater than 1 terabyte.
Before you can create a multiterabyte UFS file system, verify that you have done either of the following:
Created a multiterabyte disk partition with the format utility or the Solaris installation utilities.
Set up a multiterabyte volume with Solaris Volume Manager.
Become superuser.
Create a multiterabyte UFS file system on a logical volume.
For example, this command creates a UFS file system for a 1.8 terabyte volume.
# newfs /dev/md/rdsk/d99 newfs: construct a new file system /dev/md/rdsk/d99: (y/n)? y /dev/md/rdsk/d99: 3859402752 sectors in 628158 cylinders of 48 tracks, 128 sectors 1884474.0MB in 4393 cyl groups (143 c/g, 429.00MB/g, 448 i/g) super-block backups (for fsck -F ufs -o b=#) at: 32, 878752, 1757472, 2636192, 3514912, 4393632, 5272352, 6151072, 7029792, 7908512, Initializing cylinder groups: ............................................................................ ........ super-block backups for last 10 cylinder groups at: 3850872736, 3851751456, 3852630176, 3853508896, 3854387616, 3855266336, 3856145056, 3857023776, 3857902496, 3858781216, # |
Verify the integrity of the newly created file system.
For example:
# fsck /dev/md/rdsk/d99 ** /dev/md/rdsk/d99 ** Last Mounted on ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups 2 files, 2 used, 241173122 free (0 frags, 241173122 blocks, 0.0% fragmentation) # |
Mount and verify the newly created file system.
For example:
# mount /dev/md/dsk/d99 /bigdir # df -h /bigdir Filesystem size used avail capacity Mounted on /dev/md/dsk/d99 1.8T 64M 1.8T 1% /bigdir |
