  1. When jumbo frames are enabled (MTU >1500), I can't access the web GUI from the public network. Reducing MTU to 1500 restores WAN access. Local network access is unaffected and works fine even with jumbo frames enabled. How should I handle this situation? Additional info: Unraid version: 7.1.4 Unraid server is using a ConnectX-3 NIC Client machine has a Marvell AQtion 10Gb Ethernet NIC
  2. 就是这个jumbo frames开启,MTU超过1500就不能从公网访问后台,MTU降到1500可以从公网访问后台。局域网不受影响,开启jumbo frames也可以访问后台。这种情况应该如何处理? 附:Unraid使用的网卡是ConnectX-3,客户机的网卡是Marvell AQtion 10Gb某款电口网卡。
  3. 有没有什么插件可以做到把一个文件夹在所有硬盘下同步备份?防止硬盘突然挂掉。
  4. Without caching and parity, the array read speed cannot be maximized and the write speed can be maximized.In arrays with only a single disk, both read and write speeds can be maximized. Example UNRAID ConnectX-3 10GB NIC,4 ssd(sata3),no cech,no cache,no parity PC QNAP QNA-UC5G1T 5GB NIC(usb),Optane 900P SMB UNRAID /mnt/user/XXX → PC C:\ 100MB/s~300MB/s PC C:\ → UNRAID /mnt/user/XXX 400MB/s UNRAID /mnt/disk1 (or disk2 disk3...) → PC C:\ 400MB/s PC C:\ → UNRAID /mnt/disk1 (or disk2 disk3...) 400MB/s Obviously, the reading speed of the array is abnormal. I don't want to use cache because TLC SSDs are not reliable. I hope the developers can solve this problem.
  5. 在/mnt/disk1目录下读写都可以稳定400MB/s,多谢! 但是在/mnt/user下就不行。。。除了添加cache还有解吗?我就是怕缓存盘扛不住,所以放弃了缓存盘,数据盘全部采用SSD的方案。
  6. 硬件似乎没有太大问题,但是读写速度问题很大。 UNRAID是4片sata SSD,没有校验,没有缓存。网卡是 ConnectX-3光口万兆网卡。 PC是威联通5G USB外置网卡。傲腾900P硬盘。 交换机是威联通的QSW-308S 光电混合口万兆交换机。 似乎硬件都不是瓶颈。 从PC读取,写入UNRAID还算正常,可以保持400MB/s。但是从UNRAID读取,写入PC的时候速度波动非常大,最高只有300MB/s,最低掉到100MB/s,非常不稳定。问题出在哪了?搞不明白了,各位帮忙支支招,谢谢!
  7. Please forgive me for my poor English. A problem about the reading speed of UNRAID bothers me Hardware: UNRAID ConnectX-3 10GB NIC,4 ssds(sata3),no cech,no cache,no parity PC QNAP QNA-UC5G1T 5GB NIC(usb),Optane 900P PC to UNRAID:400MB/s UNRAID to PC:100~300MB/s I don't know what the problem is. Who can help me? Thank you!
  8. 1.不要用黑群晖,或任何非正版软件,这样不好。看见了我就劝一句,说不说在我,听不听在你。 2.UNRAID即是虚拟机又是文件服务器,可折腾性很强,乐趣就在这里。如果为了省钱而DIY那你要失望了,DIY试错的成本很高的,建议直接购入硬路由、品牌NAS等设备,装上就能用,简单方便还省钱。 3.UNRAID文件管理系统有很多特点,如磁盘消耗小、省电、静音等。但有一个致命的不足,那就是读写速度慢,希望LZ了解。通常的做法是用固态硬盘作为缓存盘,解决写入速度的问题。这种做法的缺点是读取速度不一定能够解决,而且缓存盘的使用寿命也令人担心。我建议的做法是无缓存盘,数据盘全部使用固态硬盘,搭配万兆网络使用。而且我说过了DIY不省钱。
