I am using raidctl on a v440 disk and noticed it resyncs after every boot, which takes about 30 minutes because of the size of the partition. I am concerned with what happens during the resync if "writes" happen to the disk before it is complete?
Any info would be helpful.
Thanks (0 Replies)
Can anyone could tell me what is the meaning of this problem:
Last successful check resync is greater than min sync interval (1195785433 > 7200)
And what can do to solve this problem.
Thank you..Please HElp me! (4 Replies)
Hi All,
i am aware that there is a difference between:
1. rsync -n -av /tmp .
2. rsync -n -av /tmp/ .
I would like to do the first option. But if i use a variable (rsync -av $log .), the command behaves like a second option (with the trailing slash)
Is there any way to use a... (2 Replies)

In my infinite lack of wisdom, I brought a Solaris 10(Sparc, 64 bit ) system down to init 1, detached a metadrive so that I could run format->analyze->refresh on it, and then reinit'd and reattached it .
It started syncing the drive as it's a submirror of a mirrored drive, which happens... (8 Replies)

shell-quote
SHELL-QUOTE(1p) User Contributed Perl Documentation SHELL-QUOTE(1p)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
