pre-pend log timestamp
Posted on
Adds a timestamp before alog from a script
awk -v sec=$(date -u +%s) '{print strftime("%Y-%m-%d %H:%M:%S",sec), $0; fflush();}'
in cron :
awk -v sec=$(date -u +\%s) '{print strftime("\%Y-\%m-\%d \%H:\%M:\%S",sec), $0; fflush();}'
So :
# echo hello world | awk -v sec=$(date -u +%s) '{print strftime("%Y-%m-%d %H:%M:%S",sec), $0; fflush();}'

Fix Raid on LSI controllers when a disk is shown as ubad
Posted on
This can be done with both megacli and storcli.
Since the way forward is storcli this how to will be based on that.
storcli /c0 show all
Drive Information : ================= ------------------------------------------------------------------------------- EID:Slt DID State DG Size Intf Med SED PI SeSz Model Sp ------------------------------------------------------------------------------- 8:1 7 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U 8:2 6 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U 8:3 5 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U
.
. 8:14 4 UBad - 223.062 GB SATA SSD N N 512B INTEL SSDSC2CW240A3 U -------------------------------------------------------------------------------
Say 8:14 is marked a Ubad. (Unconfigured bad)
storcli /c0 /e8 /s14 set good
storcli /c0 show all
It should now have the disk marked as Ugood ( Unconfigured Good)
------------------------------------------------------------------------------- EID:Slt DID State DG Size Intf Med SED PI SeSz Model Sp ------------------------------------------------------------------------------- 8:1 7 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U 8:2 6 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U 8:3 5 Onln 0 465.25 GB SATA HDD N N 512B WDC WD5003ABYX-01WERA1 U
.
. 8:14 4 uGood F 223.062 GB SATA SSD N N 512B INTEL SSDSC2CW240A3 U -------------------------------------------------------------------------------
storcli /c0 -/fall show
Controller = 0 Status = Success Description = Operation on foreign configuration Succeeded FOREIGN CONFIGURATION : ===================== ---------------------------------------- DG EID:Slot Type State Size NoVDs ---------------------------------------- F - Cac0 Frgn 223.062 GB 1 ---------------------------------------- NoVDs - Number of VDs in disk group|DG - Diskgroup Total foreign drive groups = 1
This would show an external configuration which needs clearing.
Now we need to clear the config data from the previous RAID conf cached on the disk.
storcli /cx /fall import
This will clear the foreign config and start the rebuild.
To follow the rebuild :
storcli /c0 /e8 /sall show rebuild
Controller = 0
Status = Success
Description = Show Drive Rebuild Status Succeeded.

Or for one drive in particular:
storcli /c0 /e8 /s14 show rebuild

Status = Success
Description = Show Drive Rebuild Status Succeeded.

That’s it.
[ NOTE : ] Rebuild might take more than 1 day in default mode…. Just saying be patient.

Decoding parameters in Bash script (1 space delimited)

This is a small script that takes a bash command and decodes the parameters in non sequential order except definers.
#!/bin/bash
if [ "$#" -ne 1 ] || ! [ -d "$1" ]; then
echo "Usage: $0 " >&2
exit 1
fi
while [[ $# > 1 ]]
do
key=”$1″
echo $key
shift
case $key in
-c|–color|color)
COLOR=$1
