*1. NFS mount issue*
Hostname : *dss03*
Model : *SR2612UR*
Mount clients : *Solaris, Linux*
Share Volume : *lv0001/vol1, lv0002/vol2, lv0003/vol3*
Working Job : *upd_0882-DSS-V6.upd patch applied*
*Working history*
1-a. NFS clients not unmount
1-b. Service network cable unplug
1-c. Admin network 100.100.101.223 using
1-d. Patch applied
1-e. dss03 NFS service check (Online)
1-f. Service network cable connect
*NFS client problem*

* mount option (# mount -F nfs -o rw,soft vector:/vol*[x]* /*[mountpoint]*
)
-------------------------------
for Linux:
NFS mount is gone after patch applied
Linux system rebooting or mount command use
* mount option (# mount -t nfs -o rw,soft vector:/vol*[x]* /*[mountpoint]*
)
-------------------------------
*For Solaris, the size of share has changed.*
*For Linux, the mount point is gone.*
*Why is this phenomenon?*
*2. Data replication issue*
Hostname : *dss01, dss02*
Model : *SR2612UR, SR1600UR*
Problem Logical Volume : *lv0001 (3500 GB)*
Problem Share Name : *engr*
Problem Data Replication : *lv01_engr*
*Problem Description*
a. dss01 and dss02 is service and backup system
b. File view: task_reverse.log

d. Check system (lv0001(dss01) 95% used, lv0001(dss02) data full)
e. "lv01_engr" data replication running fail
*The original data is small. Why should not data replication?*
* Current lv0001(dss02) is data replication success after 650GB resizing
