RE: Legato Clienk Pak for Netapps

Hi Scott, > Just received the new client pak for Netapps. Much to my chagrin, I find > out it doesn't support the F500 series filers. Anyone know why this is the > case? Its due to bug 13252, a description is online. Unfortunately, we had a strange JVM/platform interaction: Under Data ONTAP Release 5.3 or 5.3.1, running NDMP or other Java-based software on F520 or F540 systems can cause system panics or watchdog resets due to an interaction between the Java runtime environment and the F520/F540 hardware/firmware. This has been resolved in Data Ontap 5.3.4. Legato are going to certify 5.3.4R1, due in a few weeks, with the Client Pak, which will then also support F500 series filers.

Comrades, Just received the new client pak for Netapps. Much to my chagrin, I find out it doesn't support the F500 series filers. Anyone know why this is the case?

Hey gang.... I just heard from the guy that does our shows: NetApp will be having a reception on Tuesday evening from 8-12 at the Schooners bar in the Sheraton. Have Fun!

I'd like to support this proposal. As many of you know, there are a number of bars on Pine St. They're uphill from the convention center, so the return trip will be on gravity-assist. I'd like to recommend to NetApp that they take steps to provide enhanced beverage throughput for this year's hospitality suite. 1. More blenders (N + 1 blenders?) 2. A caching system; just like DLT tape operations, beverage production is most efficient when given the opportunity to continue streaming despite momentary breaks in demand. The cache also helps minimize the impact of the high-latency nature of pina colada/margarita blending. 3. Hopefully, metrics from last year were saved in order to provide for predictive engineering. -- Benjy Feen | benjy(a)feen.com | http://www.monkeybagel.com

Doubled directory sizes
by tkaczma＠gryf.net 04 Nov '99

04 Nov '99

Could someone point me to a piece of documentation which explains why the directory files double in size between say Auspex and the NetApp? One of my users is complaining that now that we moved his directory all of the directory files doubled in size overnight. Tom

Howdy- The other, less likely possibility is that this user had sparse files that got filled in because the copy program couldn't/didn't cope with it. Much less probable than the other block size theories, though. Peace, dNb

Anyone know what this is about? these toasters > have been up for around 40 days or so... The syslog messages result from a misunderstanding regarding the meaning of the "timed.max_skew" option. Looking at the name of the option, one could reasonably assume that it controls how far out of whack we'll let the filer's notion of time get before we synchronize with the time server. In fact, it controls how far out of whack a timer server's time can be before the filer will no longer synchronize with the timer server. We use this field to prevent "time poisoning" of the filer by a grossly inaccurate time server. If we had it to do over again, we'd probably change the name of this option to something less confusing. So, when you specified "options timed.max_skew 2s", you were actually saying "if the time reported by the time server is more than 2 seconds away from the filer's notion of the correct time, don't synchronize to the time server." You can eliminate these messages, and get the filers back into synch with the time server by setting "timed.max_skew" to something like 30 minutes (30m). Sam

Huh.... I've been running 5.3.2R1 since Aug 12th, and I had set up the timed to : timed.enable on timed.log off timed.max_skew 2s timed.proto ntp timed.sched hourly timed.servers 205.246.15.5 Today, I started seeing in my syslogs : ..... Tue Nov 2 10:10:42 CST [Java Thread]: TimeDaemon: NTP server '205.246.15.5' reports that the time is Tue Nov 02 10:14:45 CST 1999, for both of the toasters.
