GPT and inode errors
Posted: 2017/12/18 20:48:51
Please forgive any errors or lack of information in this post as I am new to Linux. I am running CentOS 5.5 (Final) - I know it's old but can't upgrade at this time due to a limitation with an application. I have a QNAP NAS with an iSCSI LUN this app accesses. It's been working fine for well over a year but lately my app can't access any data on it. I was getting input\output errors when trying to run "du -hc" on the system which led me to look at the /var/log files (used dmesg command). Pertinent output is below. since this is an external drive system mounted on /mnt/iscsi3, can I run fsck against it? Thanks.
