Thanks for the detailed reply, Robert. A significant part of it seems to be suggesting that high-end array hardware from multiple vendors may be *introducing* error sources that studies like CERN's (and Google's, and CMU's) never encountered (based, as they were, on low-end hardware). If so,

2007/11/9, Anton B. Rang [EMAIL PROTECTED]: The comment in the header file where this error is defined says: /* volume is too large for 32-bit system */ So it does look like it's a 32-bit CPU issue. Odd, since file systems don't normally have any sort of dependence on the CPU type

Most video formats are designed to handle errors--they'll drop a frame or two, but they'll resync quickly. So, depending on the size of the error, there may be a visible glitch, but it'll keep working. Interestingly enough, this applies to a lot of MPEG-derived formats as well, like MP3. I had

A quick Google of ext3 fsck did not yield obvious examples of why people needed to run fsck on ext3, though it did remind me that by default ext3 runs fsck just for the hell of it every N (20?) mounts - could that have been part of what you were seeing? I'm not sure if that's what Robert

Hi Guys, Someone asked me how to count the number of inodes/objects in a ZFS filesystem and I wasn't exactly sure. zdb -dv filesystem seems like a likely candidate but I wanted to find out for sure. As to why you'd want to know this, I don't know their reasoning but I assume it has to do with the
