Operating Systems Solaris No space on device Post 302664309 by bakunin on Friday 29th of June 2012 09:54:37 AM

I am not a Solaris expert, but some things even i can see. Actually there are two filesystems full:

Code:
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0d0s0      4864825 4779400   36777   100%    /
/usr/lib/libc/libc_hwcap1.so.1 4864825 4779400   36777   100%    /lib/libc.so.1

and you will probably have to free up some space in both of them. Reboot the system to make sure there are no processes writing in open files, then delete some files not absolutely necessary. Good places to start looking are /var/log, /var/tmp, etc..

What is even more rtoublesome is the following: you said you allocated 100GB disk space and:

Code:
/dev/dsk/c0d0s0      4864825 4779400   36777   100%    /
/dev/dsk/c0d0s7      94717067 2577984 91191913     3%    /export/home

It looks like you have allocated ~5GB to "/" and ~95GB to "/export/home". I don't know what "/export/home" should be (user data are usually in "/home"), but i doubt this is a sound layout. This filesystem is nearly empty (probably it is empty and the 3% are just inodes), so i'd back it up, remove it and recreate it, preferably smaller by an order of magnitude. The space freed this way you could probably use to increase "/" to a sensible value (no idea what you want to store in there, but if everything stays as it is 6-7GB would look fine).

I hope this helps.

df

df(1B)						     SunOS/BSD Compatibility Package Commands						    df(1B)

NAME

       df - display status of disk space on file systems

SYNOPSIS

       /usr/ucb/df [-a] [-i] [-t type] [filesystem...]
	    [filename...]

DESCRIPTION

       The  df	utility  displays the amount of disk space occupied by currently mounted file systems, the amount of used and available space, and
       how much of the file system's total capacity has been used.

       If arguments to df are path names, df produces a report on the file system containing the named file. Thus `df	.'  shows  the	amount	of
       space on the file system containing the current directory.

OPTIONS

       The following options are supported:

       -a	  Report on all filesystems including the uninteresting ones which have zero total blocks (that is, auto-mounter).

       -i	  Report the number of used and free inodes. Print ` * ' if no information is available.

       -t type	  Report on filesystems of a given type (for example, nfs or ufs).

EXAMPLES

       Example 1 Using df

       A sample of output for df looks like:

	 example% df
	 Filesystem   kbytes  used  avail  capacity  Mounted on
	 sparky:/	7445  4714  1986     70%     /
	 sparky:/usr   42277 35291  2758     93%     /usr

       Note  that  used+avail  is less than the amount of space in the file system (kbytes); this is because the system reserves a fraction of the
       space in the file system to allow its file system allocation routines to work well. The amount reserved is typically about 10%; this can be
       adjusted  using	tunefs	(see  tunefs(1M)).  When all the space on a file system except for this reserve is in use, only the super-user can
       allocate new files and data blocks to existing files. When a file system is overallocated in this way, df can report that the  file  system
       is more than 100% utilized.

FILES

       /etc/mnttab    List of file systems currently mounted

       /etc/vfstab    List of default parameters for each file system
