Happy Friday, List! I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck? Also, if anyone has a line on a used/refurbished/r...

Hello all, As some of you might remember, there is a Sun Fire X4500 (Thumper) server that I was asked to help upgrade to modern disks. It is still in a testing phase, and the one UltraStar 3Tb currently available to the server''s owners is humming in the server, with one small partition on its tail which replaced a dead 250Gb disk earlier in to pool. The OS is still SXCE snv_117 so far. Early tests which have filled the UltraStar with data in a couple of single-partition...

Hi, I have an integrated soundcard and I have just bought a new sound card to play UltraStar (open source karaoke) in the 2-players mode. This game is know to work fine with wine and the last time (three years ago?) that I did this, it worked without special configuration. But it was an older version of wine, ubuntu and ultrastar and now it seems not to work. The problem is that in the &...

I'm building another server and must decide on scsi card the tekram looks very promising to me but need to know if it will be supported or not in 4.8 or 5.1. server will be used of mysql / apache. any info or suggestions as to scsi cards would be great. thx in advance. Sign, Eriq

Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server.

Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

...tion the head will hit next. This might be done by a re-mapping layer or integrated into ZFS. This works only because ZIL device are basically write-only. Reads from this device will be horribly slow. I have done some testing and am quite enthusiastic. If I take a decent SAS disk (like the Hitachi Ultrastar C10K300), I can raise the synchronous write performance from 166 writes/s to about 2000 writes/s (!). 2000 IOPS is more than sufficient for our production environment. Currently I''m implementing a re-mapping driver for this. The reason I''m writing to this list is that I''...

HI... i have 2x KXStudios 10.x, Lucid in the same PC. 2x different HDDs, but exactly same Hitachi Ultrastar. One has TangoStudio1.1-RT Kernel 2.6.xx the other has Generic Kernel 2.6.23-33 the reason for this is the FGLRX drivers that does not support -RT Kernels. one has Wine1.3.15 the other Wine1.3.26 the Generic Kernel + Wine 1.3.26 has problems with WineASIO JACK. if i could re-install 1.3.15 to te...

Hello. My box has been running flawlessly for months now, but in the last 2 days hasn't stayed up for more than 5 minutes. All this seemed to have started after I did a very very bad thing...... I ran the EXT2 to EXT3 conversion on my root filesystem. I used the "tune2fs -j /dev/sda1" to do the deed. After it completed the machine ran fine (the machine was up and serving when I

Well this is a new one.... Illumos/Openindiana let me add a device as a hot spare that evidently has a different sector alignment than all of the other drives in the array. So now I''m at the point that I /need/ a hot spare and it doesn''t look like I have it. And, worse, the other spares I have are all the same model as said hot spare. Is there anything I can do with this or
