Hi, Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X WD5000YS - 8nos) and create a file system with ext3? (CentOs4.3 64bit) The maximum I am getting is 1.24tb and fdisk returns no more space available. But when I say fdisk /dev/sda it list full size of 3.3 TB. But I can not create partitions more than 1.24TB. Any idea? Thanks Rajeev -...

I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one has about 1/3 the write speed. I can't find any difference between the systems. Both of them have the same stripe size, both have...

Dear list, I thought I'd just share my experiences with this 3Ware card, and see if anyone might have any suggestions. System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID 1 plus 2 hot spare config. The array is properly initialized, write cache is on, as is queueing (and supported by the drives). StoreSave set to Protection. OS is CentOS 4.5 i386, minimal install, default partitioning as suggested by the installer...

Dear all, I have upgraded the kernel and it took my 3w-9550sx-8LP sata raid card out of the box. It also fixed the problem of getting obsolete channel (my posting last week). Thanks for all your help and your support. Thanks Rajeev -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/c...

Hi, I've got a new server with a 3ware 9550SXU with the Battery. I am using FreeBSD 7.0-Release (tried both 4BSD and ULE) using AMD64 and the 3ware performance for writes is just plain horrible. Something is obviously wrong but I'm not sure what. I've got a 4 disk RAID 10 array. According to 3dm2 the cache is on. I even tried setting The StorSave preference to

I'm running FreeBSD 7.1-PRERELEASE over Asus P5Q motherboard. Such board comes with an nic requiring age0 driver. When the nic is under load, such trasferring big amount of data over gigabit connection (let's say some gigabyte backups), the computer hangs, sometimes with panic, sometimes freezing. Before that i was using an Intel nic with em0 driver and 7.0-Stable#2.. and that
