Is the weekly rotation really needed, or do you just need to retain a certain amount of data? Switching to hourly rotation and retaining a weeks worth or more of data would be the simplest solution. > As part of this process, I can not delete the original file since > that is being handled by the weekly log rotation and archival process. > > These files get pretty big, so IO and CPU are both concerns. Do you have plenty of space? If you do you can have syslog log the data into two files, one with a weekly rotation and one daily. -- Greg

And do what? Put them on another computer? If so, try plan9port's venti archival storage system or rdiff-backup. If not, could you specify? > > As part of this process, I can not delete the original file since that is > being handled by the weekly log rotation and archival process. > > These files get pretty big, so IO and CPU are both concerns. > > Any suggestions? > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug > >

Log Rotation (Snapshot)

by Tal Cohen

I'm trying to setup a secondary log rotation mechanism on on of my production systems. Right now, the system is setup to rotate logs on a weekly basis. In addition to the weekly log rotation, I also need to take hourly snapshots (i.e. just the deltas between snapshots). As part of this process, I can not delete the original file since that is being handled by the weekly log rotation and archival process. These files get pretty big, so IO and CPU are both concerns. Any suggestions?

[OT] Solaris 10 jumpstart server

by vze284qe＠verizon.net

Hi All, Ok....so it isn't a Linux question, but... In a couple of weeks, I'm going to be building a jumpstart server at work. Can someone point me to the docs for this? I went to the SUN website and found a 240 page pdf file about setting up a jumpstart server. It was REALLY hard to follow. Any help would be appreciated. TIA... -Chuck

Re: [Wlug] KVM to SUN converter??

by John Stoffel

Sun had gone away from this by the time of the Ultra1 as I recall. It was a stupid optimization from the realization that most DB-25 serial ports only used 8 signal lines max, so it was simple to just add another driver chip on un-used lines. Then someone smarter said "let's just use a DB-9 instead" and the problem was solved. Alot of middle old Suns have one DB25 and one DB9 serial port. But these are all around 10 years old.

These systems used to have an adapter that would either split the port into two or a DB25-to-RJ45 connector made to use only one.
