Does anyone know the maximum size of the root filesystem in SCO 5.0.7.?
It used to be 1GB max. SCO 5.0.7 with Development System does not fit in 1GB.
Is there a limit or has it been removed and the documenation just was not updated?
TIA,
Dan (2 Replies)

Hello everybody, a very basic question.
Inspite of me deleting huge files in a filesystem(AIX 5.3) in oracle folder, the filesystem when i check using df -k still shows 100% full. Does that mean there is a process still pointing to the files which i deleted. how do i work around this.
Thanks!... (3 Replies)

In our shop we have to run a batch cycle. Every so often while we are running batch we get a filesystem full situation that causes batch to stop or slow down. Anyway, the practiced procedure is to look for large files and zip them. This takes a lot of time. We are in a sun solaris environment. What... (1 Reply)

Hello,
in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ... (4 Replies)

switch_root
SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)
NAME
switch_root - switch to another filesystem as the root of the mount tree
SYNOPSIS
switch_root [-hV]
switch_root newroot init [arg...]
DESCRIPTION
switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
RETURN VALUE
switch_root returns 0 on success and 1 on failure.
NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR

chroot(2), init(8), mkinitrd(8), mount(8)

AVAILABILITY
The switch_root command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
