This section describes new file system features in the Solaris release.

• File System Monitoring Tool (fsstat)

• Oracle Solaris ZFS File System

File System Monitoring Tool (fsstat)

Oracle Solaris 11 Express: A new file system monitoring tool, fsstat, is available to report file system operations. You can use several options to report activity, such as by mount point or by file system type.

For example, the following fsstat command displays all ZFS file system operations since the ZFS module was loaded:

$ fsstat zfs
 new  name   name  attr  attr lookup rddir  read read  write write
 file remov  chng   get   set    ops   ops   ops bytes   ops bytes
 268K  145K 93.6K 28.0M 71.1K   186M 2.74M 12.9M 56.2G 1.61M 9.46G zfs

For example, the following fsstat command displays all file system operations since the /export/ws file system mounted.

$ fsstat /export/ws
new  name   name  attr  attr lookup rddir  read read  write write
file remov  chng   get   set    ops   ops   ops bytes   ops bytes
   0     0     0 18.1K     0  12.6M    52     0     0     0     0 /export/ws

The default form is to report statistical information in easy to understand values, such as GB, KB, and MB.

For more information, see fsstat(1M).
