tried to modify a file in a way restricted to the file’s owner or to the superuser.
Action
Switch user to root and try again.
Technical Notes
The symbolic name for this error is EPERM, errno=1.

Not supported

Cause
This version of the system does not support the feature requested, although future
versions of the system might provide support.

Action
This is generally not a system message from the kernel, but an error returned by an
application. Contact the vendor or author of the application for an update.
Technical Notes
The symbolic name for this error is ENOTSUP, errno=48.

NOTICE: /string: out of inodes

Cause
The file system specified after the first colon probably contains many small files,
exceeding the per-file system limit for inodes (file information nodes).
Action
If many small files were created unintentionally, remove them to resolve the
problem. Otherwise, follow these steps to increase file system capacity for small files:
1. Make several backup copies of the file system on different tapes (for safety).
2. Change the machine to single-user mode.
3. Use the newfs(1M) command with the -i option to increase inode density for
this file system. The following is an example:
# newfs -i 1024 /dev/rdsk/partition
4. Restore the file system from a backup tape.
Note - Increasing the inode density slightly reduces the total file system capacity.
