Hi! Today I converted my /home from Ext4 to BTRFS by reformatting and copying all over again. I created the filesystem with -l 16384 -n 16384 -d single -m single on an logical volume Intel SSD 320 and mount with compress=lzo,spacecache. Current state: merkaba:~> btrfs filesystem show failed to read /dev/sr0 Label: ''home'' uuid: […] Total devices 1 FS bytes used

Hi, as Richard Elling wrote earlier: "For more background, low-cost SSDs intended for the boot market are perfect candidates. Take a X-25V @ 40GB and use 15-20 GB for root and the rest for an L2ARC. For small form factor machines or machines with max capacity of 8GB of RAM (a typical home system) this can make a pleasant improvement over a HDD-only implementation." For the upcoming

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So

I'm considering setting up my own mailserver with Dovecot 2.0 (as soon as it's out) and SSD. I'm debating whether it's worth it or not. I have been running a mailserver with the Dovecot 1.1 train for a couple of years and it's been flawless and amazing. I'm thinking about using either FreeBSD 8.1 w/ZFS or OpenBSD 4.8-beta on a 64 GB or 80 GB SSD (Corsair or Intel) using

Has anyone installed a high I/O application such as an email server on SSD drives? Was thinking about doing two SSD's in RAID1. It would solve my I/O latency issues but I have heard that SSD's wear out quickly in high I/O situations? Something like each memory location only has X many writes before its done. Just wandering if anyone has tested it and if newer SSD's are better about

Hi, I am thinking to change sata disk for /home and I want to know if change to a SSD hd, is a good option. I have 30-40 accounts with 30-50K email in boxes. -- Saludos!! Luciano Andino GNU/Linux user #185103 Santa Fe - Argentina -----------------------------------------------

Preparing to build a small replacement server (initially built in 2005) and normally for the OS I would buy 2x500GB drives and deploy in a RAID 1 configuration. Now we have SSD drives available - does just a single SSD drive offer the same reliability or is there advantage in deploying two in a Raid 1 config? Also, what form factor / interface is best for the SSD OS boot device on a server

I have an Intel X25-M 80GB SSD. For optimum performance, I need to block align the SSD device, but I am not sure exactly how I should to it. If I run the format -> fdisk it allows me to partition based on a cylinder, but I don''t think that is sufficient enough. Can someone tell me how they block aligned an SSD device for use in l2arc. Thanks, Geoff

I mentioned here the other day that I was planning to set up a Centos 6 system using a SSD for the system drive and a regular hard drive for a data drive. My plan is to have everything that doesn't change (much) on the SSD, such as /boot, /lib, /bin and so on. I want to put /tmp and /var and /home on the regular hard drive. Now that I'm at the stage of actually setting this up I have

I just downloaded and installed R 1.6.1 on my Windows machine where I also run SAS. I want to use the 'read.ssd' function so that I can convert a permanent SAS data set into an R data frame. I downloaded and installed the package 'foreign' on my machine, which includes the 'read.ssd' function. I read the instructions, and followed the example closely in the R

Article by Jeff Layton: http://www.linux-mag.com/id/7839 anyone have views on whether this sort of caching would be useful for the MDT? My feeling is that MDT reads are probably pretty random but writes might benefit...? GREG -- Greg Matthews 01235 778658 Senior Computer Systems Administrator Diamond Light Source, Oxfordshire, UK

Anyone have any clues about how to sanitize a dead SSD? We haven't had it yet, but we're sure it's coming. Esp. since I'm a federal contractor, a dead disk gets deGaussed, but what the hell do you do with a SSD?

I'm encountering an issue booting Linux using SYSLINUX 3.62 on a FAT16 partition. There are a variety of possible causes, but I figured I'd start here. My hardware is an embedded system using an off-the-shelf COM Express module with a Phoenix BIOS. Mass storage is provided by an Intel Z-U130 Solid State Drive (aka "Intel Value SSD"). The SSD is much like a standard USB Flash

I grabbed a new SSD M4-CT064M4SSD2 from Crucial. I am disappointed. I stuck the unit in an Atom machine (zotac) with CentOS 6 on the disk. It really doesn't "feel" faster than the previous 5400 RPM drive that was in it. The SSD is giving me (in the zotac running centos 6): hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 298 MB in 3.00 seconds = 99.30 MB/sec The

Hi I have a supermicro server, motherboard is with C612 chipset and beside that with LSI3108 raid controller integrated. Two Intel SSD DC S3710 200GB. OS: Centos 7.1 up to date. My problem is that the Intel SSD Data Center Tool (ISDCT) does not recognize the SSD drives when they connected to the standard S-ATA ports on the motherboard, but through the LSI raid controller is working. Does

Hi all, is anyone on this list who dares/dared to store his index files on a MLC-SSD? Regards, Patrick

Hi all, I received my SSD, and wanted to test it out using fake zpools with files as backing stores before attaching it to my production pool. However, when I exported the test pool and imported, I get an error. Here is what I did: I created a file to use as a backing store for my new pool: mkfile 1g /data01/test2/1gtest Created a new pool: zpool create ziltest2 /data01/test2/1gtest Added the

What would the performance impact be of splitting up a 64 GB SSD into four partitions of 16 GB each versus having the entire SSD dedicated to each pool?
