Does the command fsck Dev sda1 do?
In Linux (and Mac), there is this powerful command “ fsck ” that you can use to check and repair your filesystem. “Fsck” stands for “File System Consistency checK”. This will check the sda1 partition. Note: fsck cannot be used on a mounted partition.
What does fsck Dev sda1 mean?
usually means it is mounted. You cannot repair/fix a mounted filesystem, you should first umount it. So boot from live CD, umount /dev/sda* and try to run fsck.
What is Dev SDA?
dev/sda – The first SCSI disk SCSI ID address-wise. dev/sdb – The second SCSI disk address-wise and so on. dev/scd0 or /dev/sr0 – The first SCSI CD-ROM. dev/hda – The primary disk on IDE primary controller. dev/hdb – The secondary disk on IDE primary controller.
Can you run fsck on / dev / sda?
usually /dev/sda is the whole device, and /dev/sda1, /dev/sda2 are partitions which may contain filesystem. fsck works with filesystems, so running fsck on /dev/sda is usually meaningless – you will get an error, because there will be no filesystem to check.
Is there a command run for / dev / sda?
To answer your question, no command run yet for /dev/sda. Since when above step returning partition is in used, I decided to enter init 1. Running the same command on this mode, it tells directory not exist (something like that, I missed to capture the exact msg).
Is there a fsck / Dev / SDAX-y flag?
Type fsck /dev/sdaX -y where X is the partition mentioned in the error. The -y flag answers yes to all the prompts it would otherwise have given you – you don’t have to use it but it is recommended. Once it has finished, type reboot into the prompt, and if prompted, select to continue normal startup. Highly active question.
Why is the root filesystem on / Dev / SDA1 requires a?
According to the information I found, the possible reason maybe “the system sudden power failure” or “not closed normally”. It could be failed to disk detection when we startup the computer. But I heard that it usually happens on dual systems (like Linux/Windows). I’m surprised.
