Full Discussion: Convert rootvg to scalable
Operating Systems AIX Convert rootvg to scalable Post 302931257 by rbatte1 on Monday 12th of January 2015 07:32:21 AM

I always strive to keep rootvg (or its equivalents on other OSs) empty apart from what is necessary to boot the server and get on the network. Even backup software can be installed again and good software will offer you the ability to read the backup catalogues from any tapes you have written so you can rebuild whatever it needs to get your real restores running.

For me, a rootvg should be the smallest disk you can see from the SMS menus (where you trigger the initial install or mksysb recovery from) and if local, it needs to be a pair. 36Gb (each) should be plenty. I have one server with a pair of the and only 12Gb allocated on each. I have no plans to allocate any non critical (so far as the OS is concerned) space in there. It's a waste perhaps,but I prefer to see it as a bearable cost.

We even force users we define using a home directory outside rootvg. There is no problem creating a filesystem with a mount point of /var/backup-logs or whatever, and it is probably safer that creating a separate filesystem with a symbolic link to it.


Growing rootvg might mean that you can no longer back it up with a mksysb and you will have problems restoring it too as your requirements are bigger than usual.

rootvg mirrored

I want to increase the size of /tmp by 1GB I know that the command is chfs -a size=+1G /tmp But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks. Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ? Please advise. (1 Reply)

MKFONTSCALE(1)						      General Commands Manual						    MKFONTSCALE(1)

NAME
mkfontscale - create an index of scalable font files for X SYNOPSIS
mkfontscale [ -b ] [ -s ] [ -o filename ] [ -x suffix ] [ -a encoding ] ... [ -f fuzz ] [ -l ] [ -e directory ] [ -p prefix ] [ -r prefix ] [ -n prefix ] [ -- ] [ directory ] ... DESCRIPTION
For each directory argument, mkfontscale reads all of the scalable font files in the directory. For every font file found, an X11 font name (XLFD) is generated, and is written together with the file name to a file fonts.scale in the directory. The resulting fonts.scale file should be checked and possibly manually edited before being used as input for the mkfontdir(1) program. OPTIONS
-b read bitmap fonts. By default, bitmap fonts are ignored. -s ignore scalable fonts. By default, scalable fonts are read. If -b is set, this flag has the side effect of enabling the reading of fonts.scale files. -o filename send program output to filename; default is fonts.scale if bitmap fonts are not being read, and fonts.dir if they are. If filename is relative, it is created in the directory being processed. If it is the special value -, output is written to standard output. -x suffix exclude all files with the specified suffix. -a encoding add encoding to the list of encodings searched for. -f fuzz set the fraction of characters that may be missing in large encodings to fuzz percent. Defaults to 2%. -l Write fonts.dir files suitable for implementations that cannot reencode legacy fonts (BDF and PCF). By default, it is assumed that the implementation can reencode Unicode-encoded legacy fonts. -e specifies a directory with encoding files. Every such directory is scanned for encoding files, the list of which is then written to an "encodings.dir" file in every font directory. -p Specifies a prefix that is prepended to the encoding file path names when they are written to the "encodings.dir" file. The prefix is prepended literally: if a `/' is required between the prefix and the path names, it must be supplied explicitly as part of the prefix. -r Keep non-absolute encoding directories in their relative form when writing the "encodings.dir" file. The default is to convert rel- ative encoding directories to absolute directories by prepending the current directory. The positioning of this options is signifi- cant, as this option only applies to subsequent -e options. -n do not scan for fonts, do not write font directory files. This option is useful when generating encoding directories only. -- end of options. SEE ALSO

The format of the fonts.scale, fonts.dir and encodings.dir files is documented in the mkfontdir(1) manual page. Mkfontscale will overwrite any fonts.scale file even if it has been hand-edited. mkfontscale -b -s -l is equivalent to mkfontdir. AUTHOR
The version of mkfontscale included in this X.Org Foundation release was originally written by Juliusz Chroboczek <jch@freedesktop.org> for the XFree86 project. The functionality of this program was inspired by the ttmkfdir utility by Joerg Pommnitz. X Version 11 mkfontscale 1.0.7 MKFONTSCALE(1)
