Glad to hear that

Great sir 🤙

Welcome

Instead of directly commenting out the file system (FS), we can first run mount -a. Then, we’ll check which FS is causing issues during boot. After that, we can take a backup, comment it out in fstab, and proceed with the reboot.

[@650kdub]

You csn always verify with mount -a too before booting. If there are no errors, your good to go.

[@kayithisampath6427]

Hi Sir, Thanks for the explanation.. Is it the only potential reason for that issue or do we have any other reasons also. Because In my vmware I have faced this issue.. when I am trying to give the root password, the same screen(press ctrld to continue) appears again and again.

[@babup-i6f]

df -h hung what to do sir

[@EngrAbhishekRoshan]

Check my 100 days IT corporate bootcamp where I have explained these troubleshooting with solution in Day 59. www.abhishekroshan.com/courses/100-Days-IT-Corporate-Bootcamp--Linux-Shell-Scripting-AWS-Cloud-Devops--Automation--Monitoring----Realtime-Project-668c2c25924bab7ed1d83a78 When the df -h command hangs in Linux, it usually indicates a problem with one or more mounted filesystems. 1. Network Filesystem Issues: If a network filesystem like NFS, CIFS (Samba), or SSHFS is mounted, and the network connection is slow or down, the df -h command can hang while trying to retrieve information about that filesystem. 2,Stale NFS Handles: If an NFS server becomes unreachable or its configuration changes, the client may end up with stale NFS handles. This can cause df -h to hang while trying to access the NFS mount. 3.Filesystem Corruption: A corrupted or damaged local filesystem can cause df -h to hang as it struggles to read the filesystem's metadata. 4.Hardware Issues: Problems with storage devices, such as failing disks or malfunctioning RAID controllers, can cause df -h to hang while accessing the affected disks. 5.Automounter Issues: If automounter (like autofs) is in use and it is slow to mount filesystems, df -h might hang while waiting for these mounts to complete. 6.Large or Slow Mount Points: If there are very large filesystems or slow external drives connected, df -h might take a long time to complete as it processes these filesystems. Troubleshooting Steps: Check for Network Issues: If network filesystems are mounted, check the network connection to the servers. Unmount Stale Filesystems: Try to unmount the problematic filesystems using umount or umount -f for forced unmount. Check dmesg: Run dmesg | grep -i "error" to check for hardware or filesystem errors. Use strace: Run strace df -h to see where the command is hanging. Isolate the Issue: Try running df on individual mount points to identify which one is causing the hang, e.g., df /.
