Hi Guys, Thanks for providing the forum to check the issue, I already got really helpful responses and need one more help wrt to EXT4 log messages coming in /var/log/messages file 1) I have iSCSI device attached to my VM 2) Copied and extracted files in the attached device 3) Unmount and disconnected the device, post disconnect operation I can see lots of EXT4 file system errors in /var/log/messages file, attaching the same (err.txt) for review. I am not sure what these log messages are correspond to as the device was already disconnected at Feb 1:22:42, but the ext4 log messages came after that, can you please review and share your findings. Any help is appreciated Thanks, Alok
