  1. 今天早上就刚才重启了一下unraid,结果启动不了了,插上显示器看到是Unraid没有引导成功,显示是:

    “Reboot and Select proper Boot device

    or Insert Boot Media in selected Boot device and press a key"

    看着我心想应该是U盘不行了,于是拔下来插到别的电脑上看看,结果在别的电脑上可以正常识别和打开,然后我重新弄了一下那个make bootable,插回原来的主机上,还是启动不了显示的是同样的提示。

     

    请问大佬们这是不是U盘挂了,还是可能别的什么问题?

  2. 我的理解:

    首选:文件会全部移动到缓存中,使用的时候也是优先从缓存里面读取或者写入,缓存中和阵列中的文件并不是实时同步的,二十自行设置好计划比如半夜来同步(一般使用时是从缓存同步到阵列里去),相当于有速度也有安全。唯一注意的是自己确保缓存盘容量不要不够,否则完蛋。

    仅:文件就只会在缓存中,设置成仅的文件夹就和阵列没关系了,要是缓存盘损坏了,文件也就丢失了。

    理解对吗?

    我的需求:给虚拟机,docker和system文件放缓存里加速,增加一些运行性能,但是万一缓存盘损坏,希望我的docker/虚拟机文件不会丢失,所以该用首选请问大佬是不是这样。

    还有一个问题,关于“mover不会移动当前正在使用中的文件“,我想请教一下,意思是不是那如果我的一些docker和虚拟机是7*24小时一直运行的,那是不是就变成有一些文件永远没机会被mover从缓存盘备份到阵列去? 是不是其实文件安全也并不是特别的保险?  最安全的还得是隔几天把所有docker/虚拟机关了然后mover一次?

    如果有朋友可以帮忙解惑的话真的非常感谢。

    就你的問題,我也想跟大家討論一下。

     

    數據安全有否保障?這個問題,很難會有一致答案,因為esxi,黑裙,白裙,unRAID,各系統上的功能,既重疊又不盡相同。且而,每個人對數據安全的定義和方法都不一樣。

     

    但我們可以從另一個角度去想數據安全問題。試想想如果你的戴爾底板壞了,你即時可以取回的數據是甚麼?答案是你unRAID上的數據,那unRAID有對你的數據安全作出保障。言而在黑裙上的Raid1,除非找到一模一樣的底板調換,否則找個新電腦由0到1,裝exsi及黑裙再在黑裙上做修復,在操作零失誤的前題下,才可取回Raid1上的資料。那其實esxi上的黑裙,有保障到你的資料嗎?

     

    數據安全的問題,又回歸到數據備份方案這裡,方案很多,各有各好,各有長處短處,真的視乎個人需要及場景。但防範近年黑客勒索軟體針對Nas的攻擊,方案中最好還是要包括“外置硬盤備份”方法。

     

    現在試回答你的問題:

    1)如果備份方案中,不管是白裙unRAID或其他Nas,如另外有獨立於系統(硬件及軟件)的備份方法,這才真正有資料安全保障。

    2)用unRAID一定要跟SSD Cache並用。UnRAID陣列是用來放資料的,系統在SSD Cache上跑。看你的資料主要是電視電影,單盤的讀取速度卓卓有餘。看不到你exsi跑黑裙中的Raid1比單盤快多少。

    好思路谢谢

  4. 朋友们,大佬们。

    我现在的配置算是一个伪All In One,具体是这样的:

    主机是戴尔的PowerEdgeR720八盘位,主机的系统是ESXi,

    虚拟了一个Unraid直通四个4T盘(1校验+3数据盘,就存放电视电影,以及一个jellyfin的docker,一句话就是用来看电视)

    虚拟了一个黑裙直通两个8T盘(做Raid1,就两个功能一个是drive套件,一个是active backup套件备份除了unraid,黑裙本体和下载及安机之外的所有虚拟机)

    主机上还插了三块硬盘,一块satassd(做esxi系统盘),一块2T盘(下文说用途),至此八盘尾插满,额外PCIE槽还有一块1T的nvme(用作存放除上面两个之外的虚拟机的系统盘)

    虚拟了一个windows10额外直通了2T盘当迅雷下载器,削挂器之类的。

    虚拟了一个docker运行kms,ddns之类的平时不在意但是又不可缺的小玩意。

    以及分别虚拟了一堆工作用的工具,服务在各自虚拟机里,以及一堆私服,mc,wow,rust之类的。

     

    目前运行良好,但是缺点是esxi直通导致的unraid和黑裙并不能完整的识别硬盘的smart信息,只能靠手动的在主机ssh敲命令来确认硬盘健康。

    因为上述的一个缺点,我觉得要是哪块硬盘哪天出问题了也并不能很好的提前预警,所以想请教各位如果我主机就直接安装Unraid,然后可以把除黑裙之外(群晖要么直接不要了要么重新用白群额外用在主机之外,暂时再议)的所有虚拟机和docker服务搭建在Unraid上,如果这么操作的话:

    1,数据安全有保障吗?

    2,硬盘来得及读取吗?(因为unraid阵列听说不论加入多少块硬盘,他的读取性能始终就是单盘的水平,说实话我虚拟机挺多的而且有些还挺重要的)

     

    谢谢朋友们解答。

    which definitely shows that Unraid was having problems reading the flash drive.

     

    I would conclude from that the flash drive is probably failing and needs replacing.  

     

    Do you have an up-to-date backup of your flash drive (in particular the ‘config’ folder which contains all your settings).

     

    Hi there,

    So USB drive replace it is.

     

    Yes i have the backup, and i know what to do next now, thank you very much .

  6. Hello everyone and wish all of you the best.

     

    This is the second time that it happens.

     

    Just i thought my unraid is running fine, that i noticed that i couldn`t open the smb shared folder(from unraid of crouse) by use my laptop, so i opened unraid server web console, and it said on top right corner: "Missing Key File" , as image#1

    and this is how it shows on dashboard:

    and this is show on tools/registration menu:

    3.thumb.png.ef702ac7b8315ba2ada32ee2142023fb.png

     

     And yes by the way, my key is bought legally on the official unraid page with coupon code, definitely.

     

    Please if anyone could let me know that the problem is on my key or on my USB drive?  Thanks a lot really.

    Hi, I had a lot of USB issues using esxi 6.x. there's is a big thread on the issue I and others were having from a few years ago.

     

    The best fix for me was upgrading to esxi 7.x. it fixed all my USB issues and even better allows you to direct boot the VM off of the USB drive. No more plop or vmdk's, just boots and updates like it was on bare metal.

     

    If you can't upgrade to esxi 7.x for some reason, let us know if this was a working system that just started acting up or was it after an upgrade on either eexi or unraid.

    Also check your vmkernel.log for errors to point in the right direction.

    Hi and thank you.

     

    So it is s esxi6.x issue it is.

    I think my server don`t have a official 7.x support sadly.

    FYI, it is a machine that just retired from our business so now i used it to my personal use, so i should say it is just setup and start to run both esxi and unraid.

    Again thank you for your information, now know issue is in esxi, i can start to solve it.

    Unraid的文件系统是聚合性质的,表面上看你只是将dir1下的文件移动到dir2下面,但实际上由于聚合策略,可能导致二者最终落在不同硬盘上。

     

    聚合文件系统你可以简单的想成双层蛋糕,最下层是不同的磁盘,而上层则是你在unraid中创建的一系列文件夹

     

    如果你想更进一步的控制落盘策略,可以在包含相应文件的磁盘下进行mv操作

     

    比如

     

    mv /mnt/user/disk1/dir1 /mnt/user/disk1/dir2

     

    谢谢

    请看我的截图,第一行是校验盘,第二行磁盘,最后一行应该是统计吧。
    我做的只是把文件从一个共享文件夹移动到另一个共享文件夹里面去,按照这个截图里看下来么其实也没有确实移动到另一个磁盘里去,那为啥不跨磁盘的文件移动不能像windows一样瞬间完成呢而是一本正经的在那里又在磁盘写了一遍?
    真心求教谢谢。
    或者有没有什么方法可以避免这样重新磁盘写一遍呢?

    先在unraid设置里预配证书。

    会在U盘/config/ssl/certs下面生成一个certificate_bundle.pem文件。

    把腾讯云nginx证书的.crt和.key文件复制粘贴进来保存,字段、长度不一样无所谓,直接就按照证书+key的顺序从上到下覆盖进来就可以。

    保存,重启unraid,就好了。

     

    谢谢,我还把certs下别的证书都删了, 现在可以了,感谢

    确实,我修改了那个文件重启之后就变成自己证书了。

    我用了腾讯云的Nginx证书,把bundle.crt和.key拼在一起覆盖就可以了。

    你好我也是腾讯云的nginx证书,也是拼了替换了还是不可以

    Question for those using ESXi. I understand the free version only support 8 vCPUs.  If I am running a dual processor configuration, with 8 cores and 16 threads each, for a total of 32 threads and 16 cores... can I utilize all of these in one VM on the free edition?

     

    Can`t,   setup 16 cores vm ok, but can`t start it.

  13. Hello everyone, and greeting to all of you.

     

    I have a problem here and it is raleted to my usb port(s):

    It is whenever i try to poweroff and then poweron unraid(or simply rebbot), there is a chance that it will fail to boot(to be clear it is a very big chance but not 100%), and when it fails the only solution to solve it is to physically remove usb drive and then plugin again(no matter which usb port to replugin, the other ones or the original one that get removed).

     

    It becomes a problem for me as i have this setup in my office and i do not go there everyday, so i will not be able to get this solved very fast each time it happens.

     

    And here is my setup:

    *A poweredge R720 server(E5-2620v2*2,64g eccddr3 1600, plenty of HHD drives)

    *On the bare metal is a Esxi 6.5 hyperviser, and then unraid is installed as a VM in it.

    *Use plop to help vm boot from usb drives, very excellent tool by the way.

    I think that is all information i should share, let me know if you need additional info, i would be very grateful if you could help me thanks.

    直接添加USB设备不也是可以直接引导启动的吗?为什么要通过PlopKexec,没看懂

     unraid安装在esxi6.5里面,需要靠plop来从盘启动。

    还有不知道是物理机还是esxi的原因,unraid重启之后esxi有概率不能识别u盘导致unraid启动失败。
