前端批量迁移NAS存储

在实际生产中,老的NAS存储无法扩容,需要迁移到新的存储,种种原因只能前端迁移。

系统:Linux

容量:1.5T

为了减少对生产系统的影响。

1、提前将老的存储数据备份到新的存储上;

2、正试割接存储时,增量更新提前备份之后生成的目录及文件;

备份老的存储数据到新存储上shell。

#!/bin/bash
#
#20191211
#cp -a 
PATHOLD='/opt/old'
PATHNEW='/opt/new'
PATHLIST='
AA
BB
CC
'
for OPATH in $PATHLIST
do
if [ ! -d $PATHOLD/$OPATH ];then
        echo "-----$PRO_PATH path no exist-------" >> mrice.log
        break
else
        \cp -a $PATHOLD/$OPATH $PATHNEW/ 
        [ $? -eq 0 ] && echo "`date` ----$PATHOLD/$OPATH ok---- " >> mrice.log || echo "`date` ----$PATHOLD/$OPATH error----" >> mrice.log
fi
done

 

增量更新目录及文件。

#!/bin/bash
#
#20191211
#cp -a 
MTEMP='/opt'
PATHOLD='/opt/old'
PATHNEW='/opt/new'
PATHLIST='
AA
BB
CC
'
#file list
for OPATH in $PATHLIST do if [ ! -d $PATHOLD/$OPATH ];then echo "-----$PRO_PATH path no exist-------" >> mrice.log break else cd $PATHOLD find $OPATH/* -type f -mtime -2 |xargs -i echo {} >> $MTEMP/mrice_temp$OPATH.txt echo "`date` ---$OPATH ----- find complete" >> $MTEMP/mrice1.log #cp file if [ -f $MTEMP/mrice_temp$OPATH.txt ];then for TEMPNAME in `cat $MTEMP/mrice_temp$OPATH.txt` do TEMPDIR=${TEMPNAME%/*} if [ -d $PATHNEW/$TEMPDIR ];then \cp -a $PATHOLD/$TEMPNAME $PATHNEW/$TEMPDIR/ [ $? -eq 0 ] && echo "`date` ----$TEMPNAME ok---- " >> $MTEMP/mrice2.log || echo "`date` ----$TEMPNAME error----" >> $MTEMP/mrice2.log else mkdir -p $PATHNEW/$TEMPDIR \cp -a $PATHOLD/$TEMPNAME $PATHNEW/$TEMPDIR/ [ $? -eq 0 ] && echo "`date` ----$TEMPNAME ok---- " >> $MTEMP/mrice2.log || echo "`date` ----$TEMPNAME error----" >> $MTEMP/mrice2.log fi done fi fi done
