[Cross-posting to ldoms-discuss] We are occasionally seeing massive time-to-completions for I/O requests on ZFS file systems on a Sun T5220 attached to a Sun StorageTek 2540 and a Sun J4200, and using a SSD drive as a ZIL device. Primary access to this system is via NFS, and with NFS COMMITs blocking until the request has been sent to disk, performance has been deplorable. The NFS server is a

My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and... Specifically for the slog and/or cache??? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I have RH 7.2 and was trying to make HP Officejet 7110 work with it. I have upgraded ghostscipt to 7.0.6 installed hpijs1.3.1 and foomatic-2.0. So in printconf-gui I was able to chose HP OfficeJet 7110 from the printers list and install hpijs driver. After sending page to print, printer is displaying message (printing) after printing page and diode On is blinking. Setting in printconf-gui

Hello list, while following this list for more then 1 year, I feel that this list was a great way to get insights into ZFS. Thank you all for contributing. Over the last month''s I was writing a little "whitepaper" trying to consolidate the knowledge collected here. It has now reached a "beta" state and I would like to share the result with you. I call it -

I'm having a problem installing CentOS 8 from a USB drive. When the installer boots from the USB, it displays the language selection screen. After I select English and continue, the installer freezes. The USB drive flashes a couple times over the next minute or so, the stops. The mouse moves the cursor, but the installer is unresponsive to either selecting QUIT or HELP. I've

Greetings, Before I get slammed, I've looked all over the internet for the answer to this (googled and more) and haven't been able to find what I'm looking for. Here's what I need. I have a server that I use to hold workstation images. I use a Linux boot CD combined with some scripts I wrote and some disk imaging software to allow me to image windows workstations. Anyway, when

I posted a thread on this once long ago[1] -- but we''re still fighting with this problem and I wanted to throw it out here again. All of our hardware is from Silicon Mechanics (SuperMicro chassis and motherboards). Up until now, all of the hardware has had a single 24-disk expander / backplane -- but we recently got one of the new SC847-based models with 24 disks up front and 12 in the

I recently got a new SSD (ocz vertex LE 50gb) It seems to work really well as a ZIL performance wise. My question is, how safe is it? I know it doesn''t have a supercap so lets'' say dataloss occurs....is it just dataloss or is it pool loss? also, does the fact that i have a UPS matter? the numbers i''m seeing are really nice....these are some nfs tar times before

Now the test for the Vertex 2 Pro. This was fun. For more explanation please see the thread "Crucial RealSSD C300 and cache flush?" This time I made sure the device is attached via 3GBit SATA. This is also only a short test. I''ll retest after some weeks of usage. cache enabled, 32 buffers, 64k blocks linear write, random data: 96 MB/s linear read, random data: 206 MB/s linear

I''m migrating to ZFS and Solaris for cluster computing storage, and have some completely static data sets that need to be as fast as possible. One of the scenarios I''m testing is the addition of vdevs to a pool. Starting out, I populated a pool that had 4 vdevs. Then, I added 3 more vdevs and would like to balance this data across the pool for performance. The data may be

To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct

Hi all, I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of their exaggerated claims of sustained performance. I was thinking about getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive, one of the STEC products, etc. Of course the key question i''m trying to answer is: is the price premium worth it? --- What is the (average/min/max)

Hi, Out of pure curiosity, I was wondering, what would happen if one tries to use a regular 7200RPM (or 10K) drive as slog or L2ARC (or both)? I know these are designed with SSDs in mind, and I know it''s possible to use anything you want as cache. So would ZFS benefit from it? Would it be the same? Would it slow down? I guess it would slow things down, because it would be trying to

DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or enhanced security erase or crypto erase if supported. Other options do not erase data in remapped sectors. Chris Murphy

Hi all! I''ve decided to take the "big jump" and build a ZFS home filer (although it might also do "other work" like caching DNS, mail, usenet, bittorent and so forth). YAY! I wonder if anyone can shed some light on how long a pool scrub would take on a fairly decent rig. These are the specs as-ordered: Asus P5Q-EM mainboard Core2 Quad 2.83 GHZ 8GB DDR2/80 OS: 2 x

Hi, I''m looking to build a virtualized web hosting server environment accessing files on a hybrid storage SAN. I was looking at using the Sun X-Fire x4540 with the following configuration: - 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA drives) - 2 Intel X-25 32GB SSD''s as a mirrored ZIL - 4 Intel X-25 64GB SSD''s as the L2ARC. -
