rsync同出IO error encountered-skipping file deletion解決方法

以前は同期が発生していました:

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1650) [generator=3.1.2]

そこで同期スクリプトにrとforceパラメータを加えました.
 

# cat mirrors.sh
#!/bin/bash
###    rsync  
killall `ps aux|grep rsync|awk -F" " '{print $11}'`
killall `ps aux|grep rsync|awk -F" " '{print $11}'`
echo      `date +%F_%H%M%S`                                  >> /tmp/rsync_process.log
echo '###################            ######################' >> /tmp/rsync_process.log

#URL="rsync://rsync.mirrors.ustc.edu.cn/repo"
rsync -ravzPH --delete  --force                $URL/centos/ /data/centos/ >> /tmp/rsync_centos.log 
rsync -ravzPH --delete  --force                $URL/epel/   /data/epel    >> /tmp/rsync_epel.log   
#rsync -avzPH --delete                  $URL/ceph/ /data/ceph >> /tmp/rsync_ceph.log
echo      `date +%F_%H%M%S`                                  >> /tmp/rsync_process.log
echo '###################            ######################' >> /tmp/rsync_process.log

同期にIOerror encountered-skipping file deletionが表示されるのを見た

[root@mirrors tmp]# tail -f rsync_centos.log

IO error encountered -- skipping file deletion

同時に別のエラーが発生しました.

rsync: readlink_stat("7.7.1908/isos/x86_64/.CentOS-7-x86_64-Everything-1908.iso.RjFDl5" (in centos)) failed: Permission denied (13)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1650) [generator=3.1.2]

rsyncのパラメータをよく見てみると、次のオプションがあります.
--ignore-errors I/Oエラーが発生しても削除
(I/Oエラーが発生しても削除)

[root@mirrors bin]# cat mirrors.sh
#!/bin/bash
###    rsync  
killall `ps aux|grep rsync|awk -F" " '{print $11}'`
killall `ps aux|grep rsync|awk -F" " '{print $11}'`

はい、今のところ間違いはありません.
