  1. FYI: removed the write-cache and just made one drive to be for tranfers and one for read cache. If you remove write cache, synology will stop all your services. One of the problems getting those services back online is that PostgreSQL service will need to be started manually from SSH. Login into your box via Putty and run these commands: 1. sudo synoservice --start pgsql 2. sudo synoservice --start synoindexd Then you will be able to restart your services (begin with Synology Application Service)
  2. Just saw this in this document: https://global.download.synology.com/download/Document/Software/WhitePaper/Firmware/DSM/All/enu/Synology_SSD_Cache_White_Paper.pdf Still really doesn't say anything about manually flushing the cache. They should have done is where half of SSD cache is for read and half for write and you could flush write cache any time manually. I believe Unraid actually flushes it's write cache automatically.
  3. I noticed after the SSD write cache is full, I can no longer get 500mb/s speeds(I'm running 10Gbe). I am also starting to get errors when transferring files. Is there a way to purge the cache?
  4. Nope, just whatever the 8TB drives were cheaper - I bought. I was replacing 4TB Seagates one by one and whenever I found a deal I bought a drive. As for the NIC I think one of them doesnt work because it's not supported. I really don't care about that because I got Brocade 1020 in there so I'm mainly using that for file transfers.
  5. Doods in this thread got it figured out:
  6. We cant read your mind - we need to know what you are exactly looking for. Like - crazy CPU with 4 PCI-E ports that rips everything to shreads or tiny PC on an ITX board that sits in the background and does its own thing. Here is for example my build this year: https://ca.pcpartpicker.com/list/BDHyWb Some of the parts I had, some I didnt (bought new CPU + Motherboard + 2 SSDs).
  7. Has anyone messed around with these? Its a M.2 NVME turned to PCI-E 4X slot. https://www.amazon.ca/Anxus-Express-Adapter-Conhttps://www.amazon.ca/Anxus-Express-Adapter-Converter-Machine/dp/B078GXSFKZ/ref=sr_1_8?keywords=m2+to+pcie+slot&qid=1577265031&s=electronics&sr=1-8verter-Machine/dp/B078GXSFKZ/ref=sr_1_8?keywords=m2+to+pcie+slot&qid=1577265031&s=electronics&sr=1-8 Could be interesting to extend your hard drive collection in conjunction with: https://www.amazon.ca/IOCrest-SI-PEX40062-Port-SATA-Controller/dp/B00AZ9T41M/ref=sr_1_2?keywords=pcie+x4+adapter+sata+syba&qid=1577266580&s=electronics&sr=1-2
  8. Update: I installed the 2 SSD drives. You have to disable Sequential I/O checkmark in settings for you to be able to see writes speed up. I only got 300-400 mb/s out of them - its still better than 100-200mb/s just with normal drives.
  9. Its getting cheaper. I'm following a bunch of 10Gbe switches that are silent and have 8-12 ports on them and cost below $600-800. I dont have that much need right now so I just use DAC cable with SFP+. But RG45 10Gbe - that would be sweet network. https://www.amazon.ca/dp/B075Q66RKF/?coliid=I60HDBLQAHJFN&colid=3C6VY3V1QUSSQ&psc=1&ref_=lv_ov_lig_dp_it https://www.amazon.ca/dp/B06XX4H997/?coliid=IGNMWOREKPQQK&colid=3C6VY3V1QUSSQ&psc=1&ref_=lv_ov_lig_dp_it https://www.amazon.ca/dp/B076642YPN/?coliid=I1E785APTC8EG3&colid=3C6VY3V1QUSSQ&psc=1&ref_=lv_ov_lig_dp_it
  10. Yeah that's what I was thinking. Didnt use the right word. Since my setup has 10Gbe card, I will be hitting these drives all the time.
  11. ADATA SU800 512GB - https://www.amazon.ca/gp/product/B01K8A29CS/ref=ox_sc_act_title_1?smid=A2UXO5LPTDY3LN&psc=1 https://www.anandtech.com/show/11085/the-adata-ultimate-su800-ssd-review-128gb-256gb-512gb/7 Some ok reviews for entry level SSD. I'm not planning to run crazy loads on the machine, just need to speed up writes / reads. I will probably leave only 400GB for the cache so it has that extra space in case they blow up on me (under provisioning).
  12. Plus I bought that one for 95 CAD, now 2x of them are only $150 CAD and I'll be able to do write cache.
  13. Do you think it can be because Xpenology doesnt recognize the M.2 - meaning something happens in transit of M.2 slot so this error happens? PS: sending the hard drive back now. I dont wanna deal with this bs so just going to buy 2x 2.5" SSDs
  14. GRRR that sucks. Looks like its just a new type of drive that Synology doesnt recognize?
