Software RAID 5 on 4 2TB caviar green disks. Then 12 partitions or about 500GB, and finally LVM to use the partitions as pv, and create some vg for my needs.
My disks are /dev/sda to /dev/sdd I boot on /dev/sde which is an sd card

Code:

As you are probably aware that WD released new drives ranging from 1TB to 2TB with native support for 4K sector size. And as most of stuff written online is regarding Windows and their support for 4K, my question is has anyone already started to use it under linux?

I'm thinking about getting one of these drives:
1TB WD10EARS
or
1.5TB WD15EARS
I'm using Debian Lenny so my questions are: is fdisk automatically recognizes that that drive is 4K drive, or it totally ignores it and partition is as 512byte one? In windows if no 4K support is available it would emulate it and performance would be downgraded. Do I need to enable any specific components in kernel so 4K drive is supported? I wanted to make sure there would be no data loss if I select 4K partition type.
I have a 1TB SATA2 disk in my home Debian server. I'm planning to buy two more drives (1TB too) in order to build a RAID5. Does it make any difference if I use the SATA2 drive with two SATA3 drives? I'm getting the SATA3 with more cache (64MB) at the same price than the old one and I'm not sure if the SATA version or the cache size can impact in the normal behavior of a RAID5

I have a CentOS 5 based Linux system with a 3Ware 9550SU RAID card and four 500GB drives set up in a RAID5 array (3 in the array and 1 hot spare).
I want to 'replace' these drives with four 2TB drives without data loss. My server case has a total of 8 drive bays all hot-swap and all attached to the RAID card, this means I have four empty drive bays on the RAID card.
One thought is to put the four new 2TB drives in the empty drive bays, configure them in a new RAID5 array. Then the question is now to I "mirror" the original RAID5 array over to the new one?
This is just a thought though, I am not sure it will work. In short my question to this forum is how do I accomplish this upgrade?.
I am getting really frustrated with trying to get my RAID5 working again. I had a RAID5 array built with 4 of the Western Digital 1.5tb "Advanced Format" drives, WD15EARS. However, when copying 1.5gb dvd encoded files to the drive, I was getting speeds of ~2mb/s. When researching how to make this faster, I came across all the posts about the Advanced Format drives and how that was causing a lot of issues for a lot of people. It looked like the solution was simple enough: partition starting at sector 64 or 2048 or whatever and then recreate the RAID. However, this is not working for me.
Here are my computer specs:
Motherboard: Gigabyte GA-EP43-DS3L LGA 775 Intel P43 ATX
CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W
RAM: 4gb DDR2 1066 (PC2 8500)
Video card: ASUS GeForce 9600GT 512MB 256-bit

I have an old Athlon XP 3000 machine that I keep around as a file server.It's currently got three 1TB drives which I had setup as mdadm raid 5 on FC10. The machine's original drive held the superblock for the raid array and it just had a massive heart attack. I've searched, my biggest source being URL...I can't tell if I can reassemble the superblock info lost with the original hard drive or if I've lost it all...

While time passes, a process xfdesktop begin to use more and more memory and to free RAM i need to log out and log in again.
I tried squeeze yesterday on my virtual machine and it has 4.6 and seem not to have that bug, RAM usage is static(yes it still works when i write this and have memory usage 34492k, which is not changing for an hours of usage already), also 4.6 is MUCH better than 4.4.
i already tried adding squeeze to "sources.list" but i can see too many dependencies which should be upgraded if i install 4.6, i'm beginning to afraid it can crash entire GUI(or entire system, i can see there is libc6 required to be updated).
so I setup a raid ten system and I was wondering what that difference between the active and spare drives is ? if I have 4 active drives then 2 the two stripes are then mirrored right?

I have no drive failures but just need to recreate a raid5 set as the next free MD disk number. Originally I built a temp OS of debian on a single drive and had 4x2TB drives in a raid5 software array (MD0) this worked fine and allowed me to move all data to it, and remove our old fileserver. I have now pulled out the 4 x 2TB Raid 5 drives and created a new OS on two new 80GB drives, partioned as follows,
MD0 is now 250mb Raid1 as /boot
MD1 is 4GB Raid1 Swap
MD2 is 76GB Raid1 as /
If I turn off and push back in the 4x2TB drives I cannot see a MD3. I presume I would need to create a MD3 from these 4 drives but I dont want to mess things up as its live data. So im here asking for help, or a bit of hand holding to get it done right.
PS - Its a Debian Lenny 5.0.3 Raid1 fresh install replacing a Debian Lenny 5.0.3 on a single disk.
I know you can fail and then remove a drive from a RAID5 array. This leaves the array in a degraded state.
How can you remove a drive and convert the array to just a regular, clean array?
i was adding another disk to my raid 5, all was going well it started the reshape, got past the critical zone, worked for 20mins, but now it seems to have crashed.When i cat /proc/mdstat, or mdadm -D /dev/md0, those programes hang and dont print anything or return.from my kern.log i can see that there was an error on a disk, the raid array removed it, was going to continue the reshape but finished immediately. Anyone know what i should do?

1 - I got the array up and running on three Seagate 1.5TB HDDs, filled it up in 6 months (mostly by putting all of my stuff in one place)
2 - Unknowingly, I bought a WD15EARS HDD, partitioned it as I would any normal drive and asked mdadm to grow my array over to the new partition
3 - Worried by abysmal read/write speed, I investigated, found out how to deal with the new HDD ( here or here )
4 - Being a newbie at this, I opted to do a trial run before wiping the disk and unmount/mount the partitions, LVM layers, SW RAID array. This is there I messed up.

View 14 Replies View RelatedI have added a 10 Mbps network card to my SGI O2 MIPS workstation running Debian Lenny running the 26-2 kernel. The workstation already has an onboard NIC which is working fine.(eth0).

1. Make Menuconfig
2. Loaded an alternate kernel config file (my working kernel config file)
3. In DeviceDrivers->Network device support->Ethernet (10 or 100 Mbit)
I selected ASIX AX88796 as the help associated with this showed it as an NE 2000 clone. configured it to be a module and did make, make_modules and make_install. Edited /etc/Modules to load ax88796 and added an alias eth1 ax88796 to this file. copied the new kernel to the /boot and did a reboot, the machine booted up fine and udev -r showed the 2.6.36 kernel and lsmod showed ax88796 loaded. But, Iam not able to bring up eth1 using:-

View 2 Replies View RelatedI'm trying to install Debian/Lenny on a iBook clamshell. I couldn't seem to burn an install CD that the iBook would recognize, so I eventually copied the contents of the CD onto a self-powered USB drive and I can now get the iBook to boot off of that thru open firmware. However, when I get to the Debian installer main menu, it still won't read the CD, and apparently it does not have network drivers to install over Ethernet. Is there any way I can supply a driver for the ethernet interface (lspci reports that its a sun GEM ethernet interface) or somehow convince the installer to install from the content of the USB drive (which is a duplicate of what's on the installer CD)? Heck, if it'd be easier to get the Airport interface running to reach the Internet I'd be up for that too.

I did a bit of reading and it seems that most people suggest using badblocks to first get a list of badblocks from the drive and save it to a file. Then use e2fsck to then mark the blocks listed in the badblocks file as bad on the hard drive. My problem here is that this drive is part of a RAID5 array that hosts my OS. I wanted to confirm if this was still the correct process.I boot to my Live Debian disk, stop the raid array if it's active. Then run badblocks + e2fsck commands on the drive in question and then reboot.
