Came across a strange problem, I have a software raid1 with LV sitting on top. When I try to mirror an existing LV to a new LV with the tar command I get these error messages. mount /dev/vg00/base.centos /mnt/orig mount /dev/vg00/test /mnt/new cd /mnt/orig tar cf - ./|(cd /mnt/new; tar xf - ) ... File shrank by 406815 bytes; padding with zeros ... Read error at byte 49152, reading 10240 bytes: Input/output error Do I have data corruption? If I removed the snapshots, will the padding errors disappear? Looked at reference to these but not sure if they apply. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=152162 http://rhn.redhat.com/errata/RHSA-2005-514.html OS: CentOS release 4.1 (Final) updated to most current 4.1 release prior to 4.2 release 2 WD 40gb hd /dev/md0 /boot / lvscan: ACTIVE '/dev/vg00/lv_swap' [512.00 MB] inherit ACTIVE Original '/dev/vg00/base.centos' [5.00 GB] inherit ACTIVE '/dev/vg00/osprey.swap' [768.00 MB] inherit ACTIVE Snapshot '/dev/vg00/osprey' [5.00 GB] inherit ACTIVE Snapshot '/dev/vg00/hornet' [5.00 GB] inherit ACTIVE '/dev/vg00/hornet.swap' [416.00 MB] inherit ACTIVE '/dev/vg00/test' [5.00 GB] inherit Thanks in advance, Jesse Waters
