如何在 centos7 中解决 gpfs​​ 陈旧文件句柄

如何在 centos7 中解决 gpfs​​ 陈旧文件句柄

我正在尝试让一些多集群事物在我们的两个 GPFS 集群之间工作。一种是存储集群(例如)gpfs01,另一种是计算集群(例如)gpfs02

gpfs02在我创建mmremotecluster并正确配置的“ ”集群中mmremotefs,但是在尝试挂载时,出现以下陈旧文件句柄错误:

[root@gpfs02 ~]# mmmount all

Thu Dec 12 18:57:14 IST 2019: mmmount: Mounting file systems ...

mount: mount gpfs02 on /gpfs/storage failed: Stale file handle.

但尝试mmlsmount我得到这个:

[root@gpfs02 ~]# mmlsmount all -L

File system gpfs02 (gpfs01:gpfs01) is mounted on 1 nodes:

192.168.1.215   gpfs01                    gpfs01        

[root@gpfs02 ~]# mmlsmount all_remote

File system gpfs02 (gpfs01:gpfs01) is mounted on 1 nodes.

[root@gpfs02 ~]# tail -f 100 /var/adm/ras/mmfs.log.latest

您必须按照以下步骤创建磁盘:

1) sdb : dd if=/dev/zero of=/sdb count=10240 bs=64k

sdc : dd if=/dev/zero of=/sdc 计数=10240 bs=64k

2)需要创建vim stanza.nsds文件

%nsd: 设备=/sdb

nsd=nsd3

服务器=gpfs01

使用=仅数据

失败组=100

池=数据

%nsd: 设备=/sdc

nsd=nsd4

服务器=gpfs01

使用=仅数据

失败组=100

池=数据

3)之后创建磁盘:

mmcrnsd -F 节.nsds -v 否

3)mmlsnsd

文件系统 磁盘名称 NSD 服务器

(空闲磁盘)nsd3 gpfs​​01
(空闲磁盘)nsd4 gpfs​​01

4) 创建文件系统和挂载点。
