[OpenIndiana-discuss] server hangs
Hi, I have SunOS 5.11 oi_148 installed on my storage server with 8 disks in raidz2 pool. It hangs about once in a week and I had to restart it. Can you help me troubleshoot it? It has some zfs volumes shared over nfs and afpd.

So the problems start with nfs and/or afpd timeouts on clients, but I still can ssh to the server. Can't read any files or logs though. Then network service disappears in a minute or few minutes, console becomes frozen and I have to do hard restart at that point. Where should I look to understand what causing this?

Well, might be the reason. 8 drivers is certainly limit too much for a stock psu. But there should be some traces, no? How did you figure out the reason for errors on your system? --Roman Daniel Kjar said the following, on 31-08-11 9:43 PM: Careful... are you overtaxing your power supply?

It's Kingston 16GB ssd drive. --Roman N Lucas Van Tol said the following, on 01-09-11 5:34 PM: What is your rpool like? I saw some bizzare behavior with a compact-flash based rpool; as the CF card got overused and got slower and slower, it eventually would hang without throwing any actual errors (just service times approaching infinity). Services that had enough information stored in memory continued to work, but anytime something read from the rpool it would hang, and services slowly died off.

And developers are not inclined much to pay attention to problems reported for old development releases, because the developers have moved on. One of the meanings of "development release" is that no hint was ever given that there was ever any intention of supporting it. The whole point of a development release is to get the bugs out of it so that a stable release can come out. And the best way for that to work is for everyone to work as a team and to be at the latest development release.

[OpenIndiana-discuss] Script to clean mess after zfs-auto-snapshot
After another big clenup on home filer during which I got terrible
headache because of zfs-auto-snapshost, I decided to ask if anybody
tried to simplified snapshot management.
If a user could list all fs with zfs-auto weekly snapshots enabled, or
count them up or be able to enable other periodical snapshot fs, that
would make a lot of sense I think.
Something like this:
asnap -f filesystem -p period {on|off|list|clean} {recursive}
Of course, all these can be done with zfs/svc/grep and combinations but
usually it gets tedious.
But I don't want to envent another bicycle, so decided to ask around.

That's exactly the problem: too overwhelming, also hard to remember commands if not working with it often.

Just a guess, but maybe time-slider reads these properties only on startup, and if you change them you need to restart time-slider (?). Worth a try.

Well, nobody else has piped in, so I guess I will, for what it's worth.
My pkginfo looks the same as yours. My logs don't show any errors, thank God. (I did a
"cat" on it, too. No errors.)
I'm not sure how helpful it is to you. The bug report you mentioned was for
more complex configurations. Mine is a a simple, default configuration.
Apparently, from what others have said on this list, you have to change the
root password before enabling the time slider -- at least for the gui, anyway,
as I understand.
I had already done that. Then I went into the gui app, and enabled Time Slider
with the defaults.
I hope this helps.

I don't have gui, that just a storage server. And it didn't complain

So I had to completely whack recursive from

#no need for recursive snapshots!
#if recursive == True:
#cmd.append("-r")
Then changed settings for auto-snapshot.xml and imported it back.
svccfg export auto-snapshot > auto-snapshot.smf
sudo svccfg import auto-snapshot.smf
Manually set false for whatever fs I didn't want snapshots
sudo zfs set com.sun:auto-snapshot:daily=false rpool/ROOT/oi_151a

Some environments don't have test/acceptance/pre-prod with similar hardware and configurations, so minimizing impact is understandable, which means patching only what is necessary. This thread has long since become pointless and fizzled, but just for the fun of it: I recently started a new job, where updates had not been applied to any of the production servers in several years. (By decree of former CIO). We recently ran into an obstacle where some huge critical deliverable was not possible without applying the updates. So we were forced, the whole IT team working overnight on the weekend, to apply several years' backlog of patches to all the critical servers worldwide. Guess how many patch-related issues were discovered. (Hint: none.) Patching is extremely safe. But let's look at the flip side. Suppose you encounter the rare situation where patching *does* cause a problem. It's been known to happen; heck, it's been known to happen *by* *me*. You have to ask yourself, which is the larger risk? Applying the patches, or not applying the patches? First thing to point out: Suppose you patch something and it goes wrong ... Generally speaking you can back out of the patch. Suppose you don't apply the patch, and you get a virus or hacked, or some data corruption. Generally speaking, that is not reversible. For the approx twice in my life that I've seen OS patches cause problems, and then had to reverse out the patches... I've seen dozens of times that somebody inadvertently sets a virus loose on the internal network, or a server's memory or storage became corrupted due to misbehaving processes or subsystem, or some server has some kind of instability and needs periodic rebooting, or becomes incompatible with the current release of some critical software or hardware, until you apply the patches. Patches are "bug fixes" and "security fixes" for known flaws in the software. You can't say "if it ain't broke, don't fix it." It is broke, that's why they gave you the fix for it. At best, you can say, "I've been ignoring it, and we haven't noticed any problems yet." 10 years ago, it was the case that something like half the support calls would have never arisen if the system was patched up to date. (I don't know the current figure for this.) OTOH, I have worked in environments where everything is going to be locked down for 6-10 years. You get as current and stable as you can for the final testing, and then that's it - absolutely nothing is allowed to change. As someone else already hinted earlier in the thread, the security design of such infrastructure assumes from the outset that the systems are riddled with security holes, and they need to be made secure in some other (external) way And the side effect would be dramatically reduced OPEX due to lower numbers of stuff that should be supporting environment. --Roman ___ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss

Given that quality 3TB NL-SAS drives cost around $250-300 a piece (and I recommend you buy good drives; don't cheap out on SATA if you want performance, reliability and peaceful sleep at night), the cost of the enclosure will, in the end, be a drop in a bucket in your overall investment.

Re: [OpenIndiana-discuss] Expanding storage with JBOD
David Scharbach said the following, on 02-01-14 1:53 PM: Supermicro may bit a bit overkill for the home server :) Although I have considered it for myself at home… We used them where I used to work and they are pretty nice for the money. For myself, I opted to go with the Norco 4220, a Tyan MB with an integral LSI-2008 based HBA, LSI based intel SAS expander card, 16GB of ECC, a low end xeon and 13 3TB cheap seagate HDDs. This setup allows for 20 hot swap bays connected to the SAS card, 2 2.5” SSDs connected to the MB via SATA for cache/zil and a slim optical drive with a spare SAS channel that I could use to connect to an external JBOD enclosure if needed. My drives have seen a maximum temp of 39C and that is when doing a full scrub with the server in my utility room in winter (furnace is on, heats the room up). I agree that cheap HDDs suck, I have returned 3 of them in a little over a year but ZFS and SMART are awesome at detecting early troubles. Just had another bark at me for uncorrectable sector errors. Resilvering my RaidZ2 production array does take a long time, but I have a RaidZ1 backup array so I would have to lose 5 of 13 drives at the same time to affect all my data. Nice part is I can still add 7 more drives to the case if needed. There are number of option if you want to assemble something like a storage server, but it's all limited if you want to connect a JBOD to an existing server. By limited I mean the cost going to be >= original equipment. Which card did you use by the way?

I don't get that comment. I don't need crazy amount of space nor throughput. Speaking about storage expansion, even HBA cards are dirt cheap, pricing on enclosures with integrated SAS expander is just nuts. Can't figure out how to add 8-12 disks externally to the storage server without paying for this 2x cost of the server itself. Depends how much you paid for the server itself. ;-) But that's kind of irrelevant. Often, the storage *is* more expensive than the rest of the server. Depends on how much storage you're adding. There's a cost for the HBA, for the drive bay, and then a cost for the disks, multiplied by the number of disks. So the disks add up quickly. I'm a fan of Sans Digital products for the price. And I'm a fan of using the disks that they recommend. Maybe something like this?

Also, the IcyBox I recommended to you is a tiny thing you can run on your desk or stick underneath a staircase out of sight. The MSA50, on the other hand, is a huge rack-mounted hunk of loud fans.

Ok, lets run the numbers for icybox http://www.raidsonic.de/data/datasheet/raidon/EN/datasheet_iS2880_e.pdf I'll probably need this model, iS2880-8S-U5D - 245$ on amazon. And probably some kind of power supply required or its supposed to work form psu of the server? 60$ What about cables and adapter? Something like this probably, with 3-4 ports for expansion farther. 100$, easy to find cheaper I think. http://www.ebay.com/itm/LSI-3ware-9650SE-8LPML-SATA-II-PCI-e-RAID-Controller-with-2x-Mini-SAS-Cables-/200989621284?pt=US_Server_Disk_Controllers_RAID_Cards&hash=item2ecbea3c24 Total ~300 + 8x2TBx80$ = ~1000 for 16TB of raw space.
