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

Hey everyone, My company is beginning to look at using SSD drives in our CentOS based servers. Does C5 and C6 support TRIM and other "required" functions for the SSD to operate?

Hi, I''ve ordered a new server with: - 4x600GB Toshiba 10K SAS2 Disks - 2x100GB OCZ DENEVA 2R SYNC eMLC SATA (no expander so I hope no SAS/ SATA problems). Specs: http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-emlc.html I want to use the 2 OCZ SSDs as mirrored intent log devices, but as the intent log needs quite a small amount of the disks (10GB?), I was wondering

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,

Hi, I'm looking for some recommendations for a "fast" fileserver regarding the hardware you use. We have different fileservers as our requirements changed over time. The "main" problem we are faced with is, that with smb (windows 7 and OS X) clients we never get really close to GBit speed on reads or writes. Using the same servers/storages with ftp, ssh, rsync, nfs we

My computer running CentOS 7 is configured to use BIOS RAID0 and has two identical SSDs which are also encrypted. I had a crash the other day and due to a bug in the operating system update, I am unable to boot the system in RAID mode since dracut does not recognize the disks in grub. After modifying the grub command line I am able to boot the system from one of the harddisks after entering the

Does BTRFS perform any journal and/or filesystem structure alignment (for benefit to SSD longevity and SSD, RAID array and large-sector device performance) at present? ext4''s Ted Tso will deliver 128KB alignment with the next release of e2fsprogs (ie 1.41.4) [1], so perhaps it''s a good idea for btrfsprogs also, if not already available?

Hi folks, For people who might be interested, here is how btrfs performs with two partitions on a single SSD drive in a RAID-1 mirror. This is on a Dell E4200 with Core 2 Duo U9300 (1.2GHz), 2GB RAM and a Samsung SSD (128GB Thin uSATA SSD).

Hello Samba Team, We are using rysnc utility for transferring ~90GB data across the machines. We noticed that for small folders, rsync is working fine but the moment we switch to 90GB folder, it gets stuck at "building file list". We even left it running overnight e.g. 16 hours but it never came out. We are using simple rsync syntax #rsync -av --delete /data1 server2:/data RPM version

Dear all, I'm using a Virtual Machine with Ubuntu 18.04 at VIrtualBox and I'm trying to build the LLVM project from https://github.com/llvm/llvm-project.git. This VM has 6 cores (from an intel core i-7 8th gen), 11GB of RAM and 300GB of storage (from a 1TB HDD) at a laptop, this is the model: MSI GS63 Stealth 8RE. Then, I'm doing exactly that this tutorial says to build LLVM:

Hi all Is it possible to securely delete a file from a zfs dataset/zpool once it''s been snapshotted, meaning "delete (and perhaps overwrite) all copies of this file"?

Hi guys, I've a problem by one of our replicated volumes. When i look on both bricks the size of them are euqal but if i take a look into the gluster quota informations 'gluster volume quota xxx list' i get a wrong usage size. I can't see any errors on my glusterfs or brick logs. Do anyone have a hint ? Cheers Heiko -- System Wizard anynines.com
