Re: Xsan re-indexing after failover Kevin Gilbert Tue Jun 09 14:01:43 2009

Excellent question, Joe. I've never allowed it to complete the rebuild of the index since it was taking so long. I brought it down and followed the steps Apple lays out in their support forum, with the volume mounted only on the MDC hosting it until the index is rebuilt. For Adam, I guess after your 48 hour reindex Spotlight works and is as fast as it should be?

All,

This is an interesting thread, as we've encountered similar issues to those reported here and in the xsanity thread (eg. spotlight works one day, doesn't the next), and also few MDC kernel panics to which we've suspected a spotlight relationship.

Regarding this failover issue, are you finding that the indexing does succeed even if the volume is mounted on client machines during the indexing period? Or must it remain restricted to the hosting MDC only, per Apple's recommendation?

Cheers,
Joe

John,
Thanks for the link to Xsanity. I had read that thread when I originally had the problems, but a lot has been added since. Since the spotlight index is stored at the root level of the Xsan volume at .Spotlight-V100, there's no way to really "sync" this between the two controllers. The Xsanity thread did shed some light:

"For instance it is known that after a failover, the spotlight feature will not work on the other controller (I believe this has something to do with the machine's GUID in the index, but I'm not entirely clear on it myself). "

Nice. They suggested in the thread to mount it read only on the other controller, but I'm a bit wary of even touching that right now. I think I'm just going to let it be, and notify my client that if the volume fails over, they will need to wait 48 hours to be able to search again.

All-
Have any of you seen the behavior where the spotlight index for the volume will be completely re-built when a failover occurs? We have a client that has ~5TB of very small files on their SAN, and it takes close to 48 hours to completely index the volume. They use spotlight searching religiously, so this is a major issue when a failover occurs. Of course, this has only happened a handful of times (on purpose) since we upgraded to Xsan 2, but it
is still very annoying.

a lot of people are annoyed by spotlight see link below

http://www.xsanity.com/forum/viewtopic.php?t=1621

Just wondering if it helps to copy the spotlight index with rsync to
the secondary mdc so that when it fails over it will not re-index
anymore. I may be wrong here.

Thanks,
-Adam
