description of problem: 在anolis8 aarch64 ecs机器上搭建了nfs，找了台可以互联的ECS作为client端，关闭了防火墙与selinux，确保了nfs-sever,nfs-mountd,rpcbind服务正常运行，进行nfs远程挂载使用，会出现挂载长时间无响应，远程挂载不上，然后将服务器再次重启后可以成功挂载。在本地目前换了两台anolis8的机器作为server端都遇到了该情况 目前我们anolis8 aarch64上 ，nightly测试的nfs测试套是TCONF状态，（nfs01 1 TCONF: rpc.mountd not running） SKIP状态，大概率看应该是有问题，请开发同学帮忙确认下。 Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: nfs server端： 1. yum install nfs-utils rpcbind 2. 配置/etc/exports文件，创建挂载点，并设置权限 cat /etc/exports /data *(rw,sync,no_root_squash) 3. systemctl start nfs-server;systemctl start rpcbind nfs client端： 1. yum install nfs-utils 2. 远程nfs挂载，例如 mount -t nfs nfs-server-ip:/data /mnt/data Actual results: [root@iZbpxxx2kdavZ ~]# mount -t nfs -vvv nfs-server-ip:/data /data mount.nfs: timeout set for Thu Apr 20 15:59:56 2023 mount.nfs: trying text-based options 'vers=4.2,addr=fs-server-ip,clientaddr=xxx,yyy.3.236' 此处长时间无响应，机器重启后才能挂上 Expected results: nfs远程挂载无异常情况 Additional info: [root@qibo-anolis8-nightly-func-arm-2 ltp]# uname -r 4.19.91-370.git.9f40b60f4419.an8.aarch64 [root@qibo-anolis8-nightly-func-arm-2 ltp]# cat /etc/anolis-release Anolis OS release 8.8 [root@qibo-anolis8-nightly-func-arm-2 ltp]# df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 7.5G 0 7.5G 0% /dev tmpfs 7.6G 0 7.6G 0% /dev/shm tmpfs 7.6G 644K 7.6G 1% /run tmpfs 7.6G 0 7.6G 0% /sys/fs/cgroup /dev/vda2 39G 23G 15G 62% / /dev/vda1 500M 6.8M 494M 2% /boot/efi tmpfs 1.6G 0 1.6G 0% /run/user/0 [root@qibo-anolis8-nightly-func-arm-2 ltp]# free -g total used free shared buff/cache available Mem: 15 1 6 0 7 13 Swap: 0 0 0 [root@qibo-anolis8-nightly-func-arm-2 ltp]# cat /proc/cmdline BOOT_IMAGE=(hd0,gpt2)/boot/vmlinuz-4.19.91-370.git.9f40b60f4419.an8.aarch64 root=UUID=69f901e7-05b1-40ca-bff0-947d6f410fe7 ro cryptomgr.notests cgroup.memory=nokmem rcupdate.rcu_cpu_stall_timeout=300 vring_force_dma_api rhgb quiet console=tty0 biosdevname=0 net.ifnames=0 console=ttyAMA0,115200n8 noibrs nvme_core.io_timeout=4294967295 nvme_core.admin_timeout=4294967295 crashkernel=0M-2G:0M,2G-8G:192M,8G-:256M [root@qibo-anolis8-nightly-func-arm-2 ltp]# lscpu Architecture: aarch64 Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per cluster: 4 Socket(s): 1 Cluster(s): 1 NUMA node(s): 1 Vendor ID: ARM BIOS Vendor ID: Alibaba Cloud Model: 1 Model name: Neoverse-N1 BIOS Model name: virt-rhel7.6.0 Stepping: r3p1 CPU MHz: 0.000 BogoMIPS: 50.00 NUMA node0 CPU(s): 0-3 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp ssbs 服务涉及的软件包详情： [root@qibo-anolis8-nightly-func-arm-2 ltp]# rpm -qa | grep nfs nfs-utils-2.3.3-57.0.1.an8.1.aarch64 sssd-nfs-idmap-2.6.2-4.0.2.an8_6.1.aarch64 libnfsidmap-2.3.3-57.0.1.an8.1.aarch64 [root@qibo-anolis8-nightly-func-arm-2 ltp]# [root@qibo-anolis8-nightly-func-arm-2 ltp]# rpm -q rpcbind rpcbind-1.2.5-8.0.1.an8.aarch64
