Degrading Performance of AWS EFS

由 ε祈祈猫儿з 提交于 2020-07-18 12:48:23
问题 We have hosted our wordpress site on aws ec2 with autoscaling and EFS.But all of a sudden the PermittedThroughput became near Zero bytes and BurstCreditBalance was becoming less day by day(from 2TB to few Mbs!). EFS size was only around 2GB!. We are facing this issue second time. I would like to know is there anyone who has similiar experience or any suggestion on this situation.Planning to move from EFS to NFS or glusterfs on comming days. 回答1: Throughput on Amazon EFS scales as a file

问题 Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . Improve this question I'm trying to find out what the performance of a large directory structure would be if deep directories were to be accessed on a shared, nfs filesystem. The structure would be excessively large, with 4 levels of nested directories, each level containing 1024 directories. (1024 at

Using AWS EFS with Docker

问题 I am using the new Elastic File System provided by amazon, on my single container EB deploy. I can't figure out why the mounted EFS cannot be mapped into the container. The EFS mount is successfully performed on the host at /efs-mount-point. Provided to the Dockerrun.aws.json is { "AWSEBDockerrunVersion": "1" "Volumes": [ { "HostDirectory": "/efs-mount-point", "ContainerDirectory": "/efs-mount-point" } ] } The volume is then created in the container once it starts running. However it has

问题 If we have a following situation: [laptop] ---- [host1] ---- [target] where host1 is reachable from the my laptop machine, the target from host1 only. We have ssh credentials to both host1 and target. On the target I have an nfs export with the following properties: /tmp/myshare 127.0.0.1/32(insecure,rw) As we can see, I can only mount it locally, from the target machine. I can set up a dynamic tunnel: ssh -J host1_user@host1 -D 127.0.0.1:8585 target_user@target but when trying: sudo

Is there a way to create a persistent volume per pod in a kubernetes deployment (or statefulset)?

问题 I'm currently creating a kubernetes deployment, in this deployment I have replicas value set at X and I want to create X volume that are not empty when the corresponding pod is restarted. I'm not using any cloud provider infrastructures then please avoid command using cloud services. I've been searching answer in kubernetes doc, and my first try was to create one huge persistent volume and one persistant volume claim per pod that are bind to the pv but it's seem's to not work...

NFS删除远程目录后的故障处理

由 徘徊边缘 提交于 2020-04-28 10:37:38
一、删除 NFS 远程文件夹 不小心删除了spark的目录，但是hadoop集群是使用 NFS 来同步spark的整个目录。 showmount 命令用于查询NFS服务器的相关信息，在所有slave上执行 showmount -e ，提示： mount clntudp_create: RPC: Program not registered rpc.mountd 命令全名叫 NFS mount daemon，执行后部分机器恢复正常，但仍有部分slave提示： clnt_create: RPC: Port mapper failure - Unable to receive: errno 111 (Connection refused) 根据以上的错误提示，可以大概知道是RPC的问题。 二、NFS 与 RPC 的关系 NFS（Network FileSystem）服务启动时会绑定一个随机的端口（至于为何要绑定随机端口而不是指定固定端口可能是为了防止冲突）， 并会通知到RPC服务（RPC服务的进程由一个叫rpcbind的程序来完成，它会绑定一个固定的端口如111），NFS借助这个随机端口来实现与客户端的文件传输与状态共享， 因此客户端一开始需要向RPC服务端询问NFS具体绑定的端口信息。整个NFS集群包含NFS和RPC两部分，并且NFS的工作依赖于RPC。 以上图片来源于： 鸟哥的

Linux下安装配置共享工具nfs

准备工作 配置好yum源，最好也把epel源配置上 准备两台服务器(247 server，241 client) 开始安装 启动并设置开机启动 配置共享目录 客户端挂载 写入到fstab 总结，nfs参数说明 rw 该主机对该共享目录有读写权限 sync 资料同步写入到内存与硬盘中,防止数据丢失 no_root_squash 客户机用root访问该共享文件夹时，不映射root用户 no_all_squash 保留共享文件的UID和GID references nfs参数参考文档 nfs参数参考文档 nfs server配置参考文档 来源： oschina 链接： https://my.oschina.net/wangzongtao/blog/3213717
