  1. no probs, just executed this but looks like no change.. should i restart array too?

  3. Hi, How about an option to mount ESXi Unraid boot drive? i'm running unRAID as ESXi VM with vmdk as boot drive. after installing plugin, it shows there are no unassigned drives, but i can mount this drive manually from telnet session.
  4. i'm on unRAID with esxi for long time too and have no plans to change this behavior first decision would be - should you move from esxi to xen. if yes, then you can think about unraid as host system.. tried citrix xenserver some months ago on my test server - for me it looks like esxi have far more configurable options.
  5. In short: - maka a new vmdk, 8GB will be ok - attach it to a another VM (not unRAID), Windows for example, format it with FAT32 - give it label UNRAID - download unRAID instalation or copy from flash all contents, make it bootable - on Windows run appropriate bat file as Admin - change drive label to something else, Unraid_boot for example - attach this vmdk to your unRAID VM and boot
  6. Thanks for replay - how you mount it? i tried SNAP and "Unassigned Devices" plugins with no luck.. i'm on unRAID V6B12 now.. I added this to my GO file. #mount boot vm hd mkdir /mnt/boothdd mount -w -t vfat /dev/sda1 /mnt/boothdd 2>&1 However, I can no longer see this drive under beta15. I may revert tonight to beta14b and see if it comes back. I did have to expand the VMDK to do the upgrade...not sure if that has anything to do with it or not. i'm sure drive is here.. when i installed "Unassigned Devices", sda disappeared from GUI/Main/Unassigned Devices section.. just used your commands from telnet session and successfully mounted my VMDK

  8. Hi, I'm wondering, are there an easy way to upgrade unRAID that is booted from VMWare disk image? what i'm doing currently: - upgrade unRAID as usual - shutdown unRAID VM, attach boot disk to another VM, manually copy content from flash to boot disk.. what i'm doing wrong? maybe are there another upgrade method rather than doing it manually?
  9. VmWare tools for unRAID V6 see here: http://lime-technology.com/forum/index.php?topic=38279

    ok, thanks for clarifying.. if i understand correctly, SANs are running on block level, and i'm wondering can you use unRAID somewhere apart of this configuration?
  11. uldise

    Multipath TCP

    ok, this mean, you have a separate SAN and another switch/router for WAN? if yes, how you combine them? sorry for dumb questions, but i have experience with common ethernet only.. but wanna learn something new

    if you go virtualisation route with unRAID(i do but with esxi), and have many virtual machines for doing many nice things which requires resources from outside too, then you reach 1GbE very fast. on the other side, if you make single virtual server for every task then there are no problems inside - guests operate at 10GbE.

    thanks for sharing and how you connect them to WAN? or do you have incoming internet connection with FC too?

    i have no expierence with fiber networking.. can you share any info from which to start? if i understand correctly, do you have fiber switch too?
  15. Are you using HW Raid volumes? i noticed similar with my array when i try to get Smart info from Raid volumes..

    Thanks for the answer. i could use bonding as you suggested if my unRAID boxes are on bare-metal. but as i wrote, there are two esxi servers in between and esxi supports only Cisco Etherchanel/HP Trunking - and those are one to one connection between two ip by design.. according to Windows, i read somewhere that new Windows 2012/Windows 8 supports NIC bonding.. but i can't confirm this, never tried.. and yes, please share your 10GbE setup please

    Hi, i just wanna post some suggestions i found about an interesting problem - how to get more from your 1GbE network and i just hope some of you maybe have similar experience and can add some more suggestions.. my hardware setup is all simple: esxi 5.5 production server -- HP 1810-24g switch -- esxi 5.5 backup server. both esxi runs unRAID guests too, more computers are connected to the same switch. both esxi servers have 4 port Intel NICs, connectted with 4 ethernet cables each to the switch. i setup a nic Teaming on both esxi, with Route based on IP hash on Load balance, and made two static trunks on HP switch. everything runs as expected - if i have more than one connection to my unRAID server for example (from my Desktop computer and from another esxi) then i can saturate more than 1GbE to my unRAID. my next goal is to try achieve more than 1GbE for single connection cos esxi/HP Nic Teaming/Trunking work per IP - if you have more than one active connection per host, you can saturate 1GbE only. i found Miltipath TCP for that(this was discussed on the Limetech forums too but very little). i setup test ubuntu guest on each of my esxi, added 4 virtual Nics to every one, added a new ubuntu kernel(via apt repository) with Multipath TCP(this is sad news - you still need custom kernel..), and measured network performance - got max 3GBit with iperf3. the only downside i found so far, it's a huge CPU eater on the senders side cos you add a new software at transport layer... if you have any suggestion about this or have similar experience, please share Thanks in advance, Uldis
  18. Yes, Raw and Non coerced sizes are different - i copy/pasted those three lines from LSI Megacli.. and used drives are 2x Seagate Desktop HDD ST2000DM001 - Hard drive - 2 TB - internal - 3.5" - SATA 6Gb/s - 7200 rpm - buffer: 64 MB i have 2x1TB Seagates (Seagate SV35 Series ST1000VX000 - Hard drive - 1 TB - internal - 3.5" - SATA 6Gb/s - 7200 rpm - buffer: 64 MB) attached to this controller too, so there are another example: Raw Size: 931.512 GB [0x74706db0 Sectors] Non Coerced Size: 931.012 GB [0x74606db0 Sectors] Coerced Size: 931.0 GB [0x74600000 Sectors] i use these 4 drives for my Unraid - 2x2TB Raid0 for parity and 2x1TB Raid1 for cache drive Edit: updated 2TB drive specs..
  19. Agree about HPA - if a drive is empty then one simple command and full power down of the drive and you are ready to go i just studied a bit about my Raid controller Dell H710P - there are option called Coercion Mode - default value 128M for my controller - an amount of "truncation" meant in previous posts (LSI recommends change this to 1G). i can set this amount to zero too but still have no mind if this helps.. For example - i have 2TB drive attached and look at the drive info from controller: Raw Size: 1.819 TB [0xe8e088b0 Sectors] Non Coerced Size: 1.818 TB [0xe8d088b0 Sectors] Coerced Size: 1.818 TB [0xe8d00000 Sectors] if i multiply sector count(it's in Hex in above example) of Non Coerced Size by 2 as with Raid0, then Sector count are still under 4TB drive sector count.. so, it all depends - different controllers have different approaches
  20. Yes and we are just waiting for more tests with these new drives - as parity and data drives as well and with Raid0 2x4TB as parity too thanks in advance!
  21. Not true about Parity - if a Raid0 array used for parity fails, you could use a whole 8TB replacement drive as it will be a largest drive just try this HPA way on your test server to test what sweets best for you.. i did that cos of performance - i have 4TB Seagate 5900RPM data drives, and with very fast Raid0 parity i can write to disk shares at full speed of these Seagates now.
  22. Hi, just did 2x2TB raid0 for my server about a month ago with two RAID cards - HP P400 and DELL Perc H710P. and in both cases 2x2TB in size was smaller than 4TB drive. solution was very simple and are discussed on the forums - make a small HPA on your 8TB drive i have a long story with migrating to that setup cos setting up HPA, you loose any existing data, so do it only with empty drives!!
  23. some update from me - when write to user share in progress, shfs process eats all available CPU!! so, are there any config for mounting user shares to plau with?
  24. attached a pick with share settings. as i noted before, when i write to this user share, a i can see a content on /mnt/cache too.
  25. Sorry for bumping a very old thread, but i have a similar problem with a cache drive. just purchased my first Plus key to test how cache drive works.. i have a small array with 2 disks and parity drive - write speeds are about 40-50 MB/s. i added a cache drive (ssd) and tried to test write speed. when i write(with dd command on the server itself) to /mnt/cache write speed is about 350 MB/s when i write to user share with cache enabled, then write speed are the same 40-50 MB/s, but writes to cache drive occur, i can see the just written file on /mnt/cache. looks like a problem are with user shares? any ideas how improve write speeds to user shares welcome thanks in advance.
