similar to: OCZ Vertex3 SSD and LSI 9211-8i (mpt2sas)

On a CentOS 6 64bit system, I added a couple prototype SAS SSDs on a HP P411 raid controller (I believe this is a rebranded LSI megaraid with HP firmware) and am trying to format them for best random IO performance with something like postgresql. so, I used the raid command tool to build a raid0 with 2 SAS SSDs # hpacucli ctrl slot=1 logicaldrive 3 show detail Smart Array P410 in Slot 1

trying to follow the ha-drbd HOWTO on the centos wiki... I prep two identical systems with centos 5, leaving some disk space unassigned (they only have one scsi drive), create /dev/sda4 partitions on each to use for the repdata... I install the modules, create a /etc/drbd.conf like... [root at svfis-blade03 ~]# more /etc/drbd.conf # # please have a a look at the example configuration file in

Dear all, actually I installed CentOS 5.4 x86_64 on 11 new Dell R710 servers. It is required to use 5.4 to be covered by the NetApp Interoperability Matrix for use of Snapdrive. All systems spit out the error message mpt2sas0: failure at drivers/scsi/mpt2sas/mpt2sas_scsih.c:4637/_scsih_add_device()! at boot time. In dmesg the complete SCSI initialization logging appears as follows: SCSI

Hello, Maybe interesting for other people googling the web: I have Schedule+ 7.0 working under Wine 20050310 (comes with Debian Sarge). This program is bundeled with all versions of Microsoft Office, (mine comes from Office95) but most of the time hidden on the CD. It can be used as a shared calendar. I copied the directory "Schedule" directly, no setup program. Important is, that you

Hi again, thanks for all the replies to the all in one with ESXi, it was most illuminating. I will use this setup at my dayjob. Now for a slight variation on a theme: N40L with ESXi with raw drive passthrough, with OpenIndiana/napp-it NFS or iSCSI export of underlying devices. This particular setup is for a home VMWare lab, using spare hardware parts I have around. I''m trying to do

Same as its brothers/sisters, it's optimized for 4 KB blocks. /* * OCZ Vertex 4 SSDs * 4k optimized */ { T_DIRECT, SIP_MEDIA_FIXED, "ATA", "OCZ_VERTEX4*", "*"}, /*quirks/DA_Q_4K Borja.

Hi I am attempting to setup Xen 4.10 with kernel 4.9.86-30 ( virt7-xen-410-testing, virt7-common-testing ) on CentOS7 After installing everything, the machine was unable to boot and hung in dracut stating it could not find its root device. The testsystem I use is a somewhat aged Dell M915 Blade (Quad opteron 61xx), using an MPT SAS controller for it's SAS boot drives. Stock CentOS 7

I''ve got two recent examples of SSDs. Their pristine state from the manufacturer shows: Device Model: OCZ-VERTEX3 # hexdump -C /dev/sdd 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 1bf2976000 Device Model: OCZ VERTEX PLUS (OCZ VERTEX 2E) # hexdump -C /dev/sdd 00000000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| *

I have the exact same issue on several Sunfire v20z (hardware LSI RAID controler). Under high IO load, the raid controler starts complaining with disk errors : [163442.483878] mptbase: ioc0: LogInfo(0x11070000): F/W: DMA Error [163445.172333] sd 2:0:0:0: [sda] Unhandled error code [163445.172338] sd 2:0:0:0: [sda] Result: hostbyte=DID_SOFT_ERROR driverbyte=DRIVER_OK [163445.172345] sd 2:0:0:0:

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

The patch below adds support for custom HTTP headers in download.file() and url(). My main motivation for this is performing basic http authentication. Some web sites do not support embedding the credentials into the URI itself, they only work if the username and password are sent in the HTTP headers. In fact specifying the username and password in the URI has been

Did the latest Centos4.x kernel break the ability to tcpdump with any amount of traffic? Machines that used to be able to keep up now show a few packets and stop - if you hit ^C they take a minute or so to do anything, then show something like: 54 packets captured 18188 packets received by filter 18070 packets dropped by kernel Before recent updates I almost never saw packets 'dropped

I've setup the CentOS version of the RH Cluster Service on a pair of centos 4.4 i386 test boxes... wanting to do high availabilty stuff. its working, I've added a virtual IP and a fiberchannel hosted e3fs file system thhat either can mount, if I manually crash or reboot one, this IP and FS mount on the other, awesome. the servers are connected to the storage via a QLogic SANbox
