[rrd-users] Re: Help! Resize difficulties.
we decided that we wanted the 5minave area to be huge (6 months) so that we could search back to a specific time to get exact readings, not averages. The only way to do that without losing current data was to resize it. I tried just resizing to the final size but it graphed a large gap where the new empty records were. I will modify the script to check the size before it resizes so it won't grow after the 6 month mark. -Original Message- From: Clifton Royston [mailto:[EMAIL PROTECTED] Sent: Friday, December 08, 2000 18:42 To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; rrd-users@list.ee.ethz.ch Subject: [rrd-users] Re: Help!

I resize RRA 0 of several RRDs every 5 minutes. I run this script with cron. It resizes every rrd in a directory. To take care of several directories with one cron job, I actually run a script that calls this script several times but the directory is different each time. This script resizes, then deletes the original, then copies the resize.rrd to the originals name. It also lists the sizes before and after. the command line is: resize-rrd ./cricket-data/path-to-rrd-files 0 GROW 1 the params are Directory, RRA, GROW/SHRINK, Records here's the script: #!/bin/bash for rrdfile in $1/*.rrd ; do echo Before ls $rrdfile -s rrdtool resize $rrdfile $2 $3 $4 rm $rrdfile cp resize.rrd $rrdfile rm resize.rrd echo After ls $rrdfile -s echo done -Original Message- From: Sean R McNamara [mailto:[EMAIL PROTECTED] Sent: Thursday, December 07, 2000 15:57 To: [EMAIL PROTECTED] Cc: rrd-users@list.ee.ethz.ch Subject: [rrd-users] Re: Help!

Now it's just a matter of waiting while my script updates all of the rrds. I'm not sure if you'd happen to know -- but, is there a convenient way to merge a backup of the the overwritten data with the current database? There is no overlapping between the two, and unfortunately there is a missing gap of about 2 weeks, but there's nothing to be done about that now.
