Is LSI SAS3081E-R suitable for a ZFS NAS ?
According to various posts the LSI SAS3081E-R seems to work well with OpenSolaris. But I''ve got pretty chilled-out from my recent problems with Areca-1680''s. Could anyone please confirm that the LSI SAS3081E-R works well ? Is hotplug supported ? Anything else I should know before buying one of these cards ? Thanks, Arnaud

Strangely slow disk
I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

Extremely slow raidz resilvering
Hello everyone, As one of the steps of improving my ZFS home fileserver (snv_134) I wanted to replace a 1TB disk with a newer one of the same vendor/model/size because this new one has 64MB cache vs. 16MB in the previous one. The removed disk will be use for backups, so I thought it''s better off to have a 64MB cache disk in the on-line pool than in the backup set sitting off-line all

[11.0.0 Release] Please help writing release notes!
Hello everyone, With the release drawing near, it would be great to get the release notes into better shape. You can see the notes from rc2 online here: https://prereleases.llvm.org/11.0.0/#rc2 The release notes are typically the first thing people look at after the release, so it's a great opportunity to highlight the work that's been done since the last release.

R can have a bit of a learning curve... There are several ways to achieve your goal - depending on what you want: test_df <- data.frame(Movie = letters, some.value = rnorm(26)) test_df$Movie[1:10] test_df$Movie[sample(c(1:26), 10)] test_df[sample(c(1:26), 10), ] Do read a tutorial or two on R - "Introduction to R" as suggested by David or something else - so you can explain the

Vista performance (uggh)
Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

greater than 8 character passwords on Unixware (IA database support)
I made some quick changes to support the IA security thing in Uniware 7.1.1. I wish I understood all of this well enough to make a proper patch to include new defines and what not. I tried and made a mess. Hopefully I can get a better grasp this weekend. The only files I changed were xcrypt.c and Makefile. Makefile needed -lcrypt and -liaf added to LIBS=. It had -lcrypto but needed -lcrypt for
