Hi Guys

One of my hard drive in my HP server machine got crashed .on it /var/log/squid/ was mounted and it is my sdc.Now i have to remove this harddrive from my machine .How can i safely umount it without stoping any of my running services.

A clue or link to some howto would be enough.

Thanks
Talat

I would not remove a hard drive without removing the power from it, turning the machine off.

To unmount a file system use umount

You'll have to be root.

I assume you still need /var/log/squid that resides on /dev/hdc but you need to remove the hard drive. Unless you have a raid array I don't know how you can do both. I guess you could do a
Partition and format another drive, make a /var/log/sqid on it and put it in the machine.
I think that you will have to unmount the whole file sys to do that though. I don't know if you can just unmount /var/log/squid, put another drive in and remount it. You may just have to get another drive ready, shut the machine off for 3 min, put the drive in, and power back up. I don't know if you can unmount /var with the file sys mounted, never tried.

Some Sys Admin may know better. If you can then use the mount and umount commands.
