solaris - Strange ZFS hidden filesystem problem

Half of my ZFS filesystems are hidden in ZFS-fuse. Here's my story:

So, I love ZFS. I used it for about six months on FreeBSD, but due to it crashing the kernel during heavy inter-filesystem IO load, I tried switching to Solaris 5.10.

That was good, but when I attempted to do an import of my Version 13 pool into its Version 4 version of ZFS, there were some heafty problems. It may have tried to correct the filesystem definitions, I don't know.

Since that version wasn't compatible with my pool, I've now switched to Ubuntu Server 10.4. That version more than supports that of my pool, but I can only see half of my filesystems. The filesystems I can see are the same as those Solaris could see.

Now, despite those filesystems not being preset in a 'zfs list' command, I can still set properties on them and I can even still mount them and read and write files, but they just plain don't show up in 'zfs list'.

I've mounted the major ones, but I'm not sure what other filesystems there are anymore (I have about eight that I can't see).

Anyone have any idea what the heck is going on? I think I might try booting back into FreeBSD 8 (I still have the main boot drive laying around for that) and see if at least it is able to view the filesystems.

I've also done a scrub while in Linux, and it found no errors with any of the data. Oddly, DMA read errors which caused problems on FreeBSD ZFS are reported by Linux, but ZFS-fuse doesn't find an error. That's a topic for another post however.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
