@EngrAbhishekRoshan 3 месяца назад

Sure .Until I upload the video of NAS you can check this video ...because NAS (Network Attached Storage) and NFS (Network File System) are related concepts but serve different purposes: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KPpUWzwMLhE.html

@ganeshpawar231 4 месяца назад

Hi sir , I have watched your all videos and made notes of it. Thanks for the all videos🎉 I have one doubt in question no 110. Sir , I did this question of lvreduce practically as you explained step by step. But after reducing the volume,i used mount -a option and showing me error of wrong fs type , bad option , bad superblovk on /lv. Since I have mentioned it in fstab file. What will be the solution further? Could you please explain shortly?

@EngrAbhishekRoshan 4 месяца назад

Yes Correct, Good Question, this issue occurs either you have not changed the partition id of the Linux FS, So change it to 8e and make sure format the file FS with mkfs.ext4 /dev/sda1. These steps you need to perform before creating PV,VG,LV. And even after this also you have doubt and your issue did not resolve than connect with me by clicking below link: ru-vid.com/show-UCn2ZGN0TEGhgoDDiT8S3m4wjoin

If we don't organize the data by using e2fsck then will it impact the data?

@EngrAbhishekRoshan 7 месяцев назад

Yes 100% because we don't know which sector of the disk data is store.

@049-sowmyapunna3 7 месяцев назад

Sir,Is that two zeros are error checks in /etc/fstab

@EngrAbhishekRoshan 7 месяцев назад

Dump: This field is used by the dump command to determine whether and how often a filesystem should be backed up. Typically, you can set it to 0 to disable backups or 1 to enable backups. Pass: This field is used by the fsck tool to determine the order in which filesystems should be checked at boot. Filesystems with a value of 1 are checked first, those with a value of 2 are checked after the ones with 1, and so on

@psankar2692 7 месяцев назад

Please make the videos for what is linux boot process, what all are the booting issue we are facing and how to fix booting issues.

0 0 will disables the check (fsck) while reboot.

@EngrAbhishekRoshan 7 месяцев назад

Yes

@saras291 7 месяцев назад

First value zero (0) represents the dump program and the second value zero (0) represents the filesystem check (fsck) for the mounting partition. For both the case if the value is set to zero (0) then the dump and filesystem check would be disabled for particular entry, if it is set to any other value than zero then it will be enabled (dump & fsck).

@EngrAbhishekRoshan 7 месяцев назад

Very good Saras
