Re: [zfs-discuss] making sense of arcstat.pl output

2010-10-01 Thread Mike Harsch
For posterity, I'd like to point out the following: neel's original arcstat.pl uses a crude scaling routine that results in a large loss of precision as numbers cross from Kilobytes to Megabytes to Gigabytes. The 1G reported arc size case described here, could actually be anywhere between

Hmm...according to http://www.mail-archive.com/vbox-users-commun...@lists.sourceforge.net/msg00640.html that's only needed before VirtualBox 3.2, or for IDE. = 3.2, non-IDE should honor flush requests, if I read that correctly. Which is good, because I haven't seen an example of how to enabling

Hi! Hi all I just tested dedup on this test box running OpenIndiana (147) storing bacula backups, and did some more testing on some datasets with ISO images. The results show so far that removing 30GB deduped datasets are done in a matter of minutes, which is not the case with 134

[zfs-discuss] Readonly attribute on file

2010-10-01 Thread Anton Pomozov
I have the smbshare on zfs volume. When I copy file with readonly attr on the share the file becomes undeletable. I can't change Read-Only attribute from Windows. I can delete it from osol only. What I need to do to avoid this situation?? (Except to do not set read-only attr to source file).

przemol, Thanks for the feedback. I had incorrectly assumed that any machine running the script would have L2ARC implemented (which is not the case with Solaris 10). I've added a check for this that allows the script to work on non-L2ARC machines as long as you don't specify L2ARC stats on

[zfs-discuss] Is there a way to limit ZFS File Data but maintain room for the ARC to cache metadata

2010-10-01 Thread David Blasingame Oracle
I'm working on this scenario in which file system activity appears to cause the arc cache to evict meta data. I would like to have a preference to keep the metadata in cache over ZFS File Data What I've notice on import of a zpool the arc_meta_used goes up significantly. ZFS meta data

Hey folks; Running on Solaris 10 U9 here. How do most of you monitor disk usage / capacity on your large zpools remotely via SNMP tools? Net SNMP seems to be using a 32-bit unsigned integer (based on the MIB) for hrStorageSize and friends, and thus we're not able to get accurate numbers for
