similar to: Hot swap SATA?

Hi, over time the requirements and possibilities regarding filesystems changed for our users. currently I'm faced with the question: What might be a good way to provide one big filesystem for a few users which could also be enlarged; backuping the data is not the question. Big in that context is up to couple of 100 TB may be. O.K. I could install one hardware raid with e.g. N big drives

HI All, I have a dilemma and I would appreciate advice 1. Get a good size case, mobo, processor, etc and put 8 hard drives it in and RAID them. (yes an 8 port SATA mobo). Running CentOS. or 2. Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? I know that RAID is not a full proof backup, but I am looking for a solution to store all of my data, projects, music,

I have a client with a handful of USB drives connected to a CentOS box. I am charged with binding the USB drives together into a single LVM for a cheap storage data pool (10 x 1 TB usb drives = 10 TB cheap storage in a single mount point). The next fun piece is how to incorporate that storage space into an existing Active Directory structure to apply AD acls for limited access. I'd rather

From: Rodrigo Barbosa <rodrigob at suespammers.org> > Btw, don't quote me on this one :) > I'm only 90% sure of the hotswapping capabilities, and less than 50% > sure about the price :) There _are_ systems with hot-swap CPUs, memory and/or, PCI[-X] slots. They are _not_ commodity and pricey, and require OS-level support. In fact, I believe Linux 2.6 has some support for

Hi all, my motherboard ma78gm is working. I am trying to get working the esata. I plug in my external driver, power cycle the external drive. then turn on my machine. My drive sda is detect as normal. however I dont see anything about any other disk. dmesg didnt show anything. Is there something special needed to activate the esata drive? Jerry

I figured the following ZFS ''success story'' may interest some readers here. I was interested to see how much sequential read/write performance it would be possible to obtain from ZFS running on commodity hardware with modern features such as PCI-E busses, SATA disks, well-designed SATA controllers (AHCI, SiI3132/SiI3124). So I made this experiment of building a fileserver by

Hi all, Space is starting to get a bit tight here, so I''m looking at adding a couple of TB to my home server. I''m considering external USB or FireWire attached drive enclosures. Cost is a real issue, but I also want the data to be managed by ZFS--so enclosures without a JBOD option have been disgarded (i.e., I don''t want to use any internal HW RAID controllers). One

Hi all, I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in

Is this possible? I want an external case with 4 HD in, each having an individual eSata cable. I plug in this case only when needed (each HD plugs into my PC separately), and do something like ">import ZFS pool" and use my ZFS raid. When done, I unplug it with ">export ZFS pool" or something similar command. This way I save energy, less noise, etc. I want it only as a

I am trying to test a new setup of NV74. I have set up the system with ZFS boot. Everything works fine until I pull a drive. The system locks up when I try to run any command e.g. zpool status. There is no communication with the server from then on. It does not even respond to pings. Setup - Supermicro SC836TQ-R800 Chassis Supermicro X7DB8 Motherboard Supermicro SAT2-MV8 SATA controller

I have a supermicro AOC-SAT2-MV8 and am having some issues getting drives to work. From what I can tell, my cables are to long to use with SATA2. I got some drives to work by jumpering them down to sata1, but other drives I can''t jumper without opening the case and voiding the drive warranty. Does anyone know if there is a system setting to drop it back to SATA1? I use zfs on a raid2 if

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: -

Hey, anyone using an LSI MegaRAID experienced "disappearing drives"...? We installed 6 new C6 servers, each with a Supermicro SMC2108 (LSI MegaRAID) controllers and 3 PX-128M5Pro SSDs ( RAID1 + hostswap). 2 weeks (and almost no activity on it, since not in production, apart from installation) later, megacli sees (based on the slot numbers): - on one server: only the 2nd disk of the RAID

I have two 500 GB drives on my system that are attached to built-in SATA ports on my Asus M4A785-M motherboard, running in AHCI mode. If I shut down the system, remove either drive, and then try to boot the system, it will fail to boot. If I disable the splash screen, I find that it will display the SunOS banner and the hostname, but it never gets as far as the "Reading ZFS config:"

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host

[ Yes, SP^M'n the list with follow-ups to myself ;-] From: Bryan J. Smith > If you are building a new system with such storage requirements, > I would really push you towards a 3Ware Escalade 8006-2 or 8506-4. When cost is supreme, then just a Escalade 7006-2 or 8006-2 with (2) [P]ATA or [S]ATA drives is what you want. It only adds ~$125 to system cost. When you want to minimize

Hi, Does anybody has any experience with e-sata on CentOS5.2? - How fast is it? Same as an internal sata? - Does it support sata-2? - Does it "hot-plug" like a USB? -- Thanks http://www.911networks.com When the network has to work

I''ve lucked into some big disks, so I''m thinking of biting the bullet (screaming loudly in the process) and superceding the SATA controllers on my motherboard with something that will work with hot-swap in Solaris. (did I mention before I''m still pissed about this?) I have enough to populate all 8 bays (meaning adding 4 disks to what I have now), so the 6 ports on the

Hi, I'm looking for a good e-SATA card, preferrently one that is supported by Linux with built-in drivers (no need to compile the modules from the vendor), or at least that the vendor's drivers are packaged with dkms or something similar that makes it easy on kernel upgrades. It's essential that the card supports hot-plugging, because we want to use it to plug backup drives and have
