Operating Systems Linux Red Hat How to resize filesystem by resizing the LUN without impact to applications.? Post 302830419 by Just Ice on Monday 8th of July 2013 05:50:24 PM

there never was a question about being able to resize a filesystem while it is running ... given that a reboot is to be avoided as much as possible, i am assuming that the processes in question are hyper-critical ...

so the issue is more -- what are the consequences of a botched process and can the company afford it? or put in another way, can you or your manager afford the risks to production?

This is actually a VxVM question. I have a volume/filesystem spread over 4*146G disks. Now I want to shrink the filesystem - which I can do using vxresize. However, I want to shrink so that two of the four disks that the filesystem occupies are removed from the volume. Can I do that? (3 Replies)

reboot(8)						      System Manager's Manual							 reboot(8)

Name
       reboot - automatic reboot procedures

Syntax
       /etc/reboot [ -n ] [ -q ]

Description
       The  ULTRIX  system is booted by loading a kernel image, usually into memory at location zero and transferring to zero.	Because the system
       is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.

       When the reboot of a running system is desired, is normally used.  If there are no users, can be used.  The command causes the disks to	be
       synced,	and  then  a multiuser reboot is initiated.  The system is booted and an automatic disk check is performed.  If the procedure suc-
       ceeds, the system is then brought up for the users.

       The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system.  A consistency check
       of the file systems will be performed and, unless the check fails, the system will resume multiuser operations.

Options
       -n   Prevents the disks from being synced.

       -q   Reboots quickly and ungracefully, without shutting down running processes first.

Files
       System code
