NetApp 收到了查找单个卷或多个卷中重复文件的请求。NetApp 提供了以下解决方案。
对于单个卷，运行以下命令：
[root@mastr-51 linux]# ./xcp -md5 -match 'type==f and nlinks==1 and size != 0' 10.63.150.213:/common_volume/nfsconnector_hw_cert/ | sort | uniq -cd --check-chars=32 XCP 1.5; (c) 2020 NetApp, Inc.; Licensed to Calin Salagean [NetApp Inc] until Mon Dec 31 00:00:00 2029 176,380 scanned, 138,116 matched, 138,115 summed, 10 giants, 61.1 GiB in (763 MiB/s), 172 MiB out (2.57 MiB/s), 1m5s Filtered: 38264 did not match 176,380 scanned, 138,116 matched, 138,116 summed, 10 giants, 62.1 GiB in (918 MiB/s), 174 MiB out (2.51 MiB/s), 1m9s. 3 00004964ca155eca1a71d0949c82e37e nfsconnector_hw_cert/grid_01082017_174316/0/hadoopqe/accumulo/shell/pom.xml 2 000103fbed06d8071410c59047738389 nfsconnector_hw_cert/usr_hdp/2.5.3.0-37/hive2/doc/examples/files/dim-data.txt 2 000131053a46d67557d27bb678d5d4a1 nfsconnector_hw_cert/grid_01082017_174316/0/log/cluster/mahout_1/artifacts/classifier/20news_reduceddata/20news-bydate-test/alt.atheism/53265
对于多个卷，请运行以下命令：
[root@mastr-51 linux]# cat multiplevolume_duplicate.sh
#! /usr/bin/bash
#user input
JUNCTION_PATHS='/nc_volume1 /nc_volume2 /nc_volume3 /oplogarchivevolume'
NFS_DATA_LIF='10.63.150.213'
#xcp operation
for i in $JUNCTION_PATHS
do
echo "start - $i" >> /tmp/duplicate_results
/usr/src/xcp/linux/xcp -md5 -match 'type==f and nlinks==1 and size != 0' ${NFS_DATA_LIF}:$i | sort | uniq -cd --check-chars=32 | tee -a /tmp/duplicate_results
echo "end - $i" >> /tmp/duplicate_results
done
[root@mastr-51 linux]# nohup bash +x multiplevolume_duplicate.sh &
[root@mastr-51 linux]# cat /tmp/duplicate_results
