Hi, I've CentOS5 box with 3ware RAID controller in it. I can't get the tw_cli command line tool to work, and smartd also barks on me. The tw_cli simply doesn't see the controller, no errors logged anywhere. When starting smartd, it is much more verbose. I'm getting a bunch of messages like this: Oct 9 22:15:15 toporko kernel: program smartd is using a deprecated...

Just you wait till you get to the MegaRAID command line! It makes tw_cli seem like echo in comparison. I found the 3ware web interface too clunky for my purposes, so I forced myself to learn tw_cli. Once I used it regularly I found it to be most...

I have the latest kernel with the drivers for my 3ware 9550SX built in. Where can I find the tools and monitoring apps for this card? Are there rpms hiding somewhere, or do I need to build it from source? -- Bowie

...different journal types * setting commit=120 - helped a little Even after these optimizations it doesn't seem like the raid array is working as it should. After a few 1GB writes (dd from /dev/zero to the raid) kjournald runs for an hour and later writes are really slow. Not only that, using tw_cli is very slow ... whereas tw_cli is superfast if kjournald is not churning away. So it goes something like this * write one 1GB file (486 MB/s) * writes another (223 MB/s) * any writes before the 120s commit kicks in, is ~200MB/s * commit kicks in and kjournald starts churning * writes are all ove...

...t-tech.com/datasheets/RR2220%20datasheet_050430.pdf Anyone know if this is any good under Centos 4.3 ? I see there is a current RHEL 3 and 4 driver. Would that driver survive kernel upgrades, I'm guessing it would being modular ? (please don't tell me that 3ware is the only make to use, tw_cli is not exactly user friendly). Anyone using this - http://www.promise.com/product/product_detail_eng.asp?segment=RAID%20HBAs&product_id=147 Promise has never given me any joy under Linux. cheers

Hi List; I just got a new server (my first **real** server). It's a dell 2900 : quad core XEON (with a spare slot for a 2nd quad core chip) 8G memory (expandable to 64G) 8 hot swap SATA HD slots onboard PERC6i RAID controller etc I initially setup the system / RAID as follows: 1) booted off the dell setup CD 2) walked through the RAID setup and formatted the drives 3) the setup bombed

Those who used 3ware cards > do know it and do use that nice feature. I never used the 3dm2 web GUI. I thought it was stupid and greatly preferred tw_cli. You can set at least scheduled verifies through tw_cli. (I don't know if you could use the 3dm2 GUI to schedule other tasks.) I only use 3dm2 to send out email alerts. I tried using MSM to send out email alerts but I got way way too many alerts for trivial events, so I ended up disabling it...

CentOS Community, What commands can I use to check the disk health of the system when LVM2 is being used on top of a RAID 10 using a HARDWARE 3ware raid card. The OS sees a hardware raid usually as one big drive. Is there a way to check the disks individually to see if any are failing, or throwing hard or scsi transport errors?

I guess your 3ware controller has to initiate this. And, what is the status of the BBU?

No, not just you. tw_cli is needlessly confusing in its command structure.

Hi, Which SATA RAID cards work natively on Centos 4.x?? I have heard that the only one supported is the 3ware cards but not sure if that requires a driver to be added or if it just works out the box.. Also would like to know of alternatives.. Thanks..

I'm looking to do a bit more monitoring of my 3ware 9550 with smartd, and wanted to see what others were doing with smart for monitoring 3ware hardware. Do you have the smartd.conf configured to test, or simply monitor health status? Are you monitoring the drive as centos sees it (/dev/sdX) or are you using the 3ware /dev/twaX for monitoring? Opinions and discussions are welcome :-P --

I need a SATA RAID PCI card that works well with CentOS and is fully supported. Mandatory features: - works with the drivers already in the kernel, no additional drivers - can do RAID 0, 1 and 5 - hotswap - allows to monitor the status of the array and of each individual drive via a script (ideally run from cron) - works with very large SATA drives Nice to have features but not mandatory: -

Greetings, I am looking for a hardware raid card that supports up to 4 SATA II hard disks with hot swap (compatible raid cage) I have short listed two LSI/3Ware cards: 1. 9750-4i 2. 9650SE-4LPML Both appear to be well supported in Linux. I would appreciate your personal experience with the CLI tools provided by LSI. Can they be configured to send email for disk failures or SMART errors? Is

...rac/puppet/tags/facter%2Crecipe does not give any clear hint on this. Maybe I should start a new page like the one for puppet-module repositories. Anyway, here are the facts: 3ware - gives information (firmware, model, make, size) about the harddisks connected to 3ware controllers (requires tw_cli) harddisks - information (firmware, model, make) for non-3ware controllers. These 2 are especially nice for those people who might have seagate harddisks in their boxes... raid - more information than in: http://reductivelabs.com/trac/puppet/wiki/Recipes/RaidFact pystone - makes a simple pysto...
