No. If you increase physical RAM you often want to add SWAP devices. Having all your directories in a single partition instead of separate filesystems can cause issues down the road. For years I've made it a point to have /boot, /root, /var and /usr separate because NOT doing so caused major issues. Usually I'll have sub-mounted filesystems as well for things I expect to use a fair amount of space. Having /root fill causing all sorts of issues that take a lot of effort to recover from (sometimes requiring a reinstall). Odd and unexpected issues can crop up. Many things like to write into /var/spool for example. I've seen issues with that running out of space when large email queues get clogged up. Another fun thing I once ran into was when logs said we were out of "space" on /var but df and other tools indicated it had free "space". It turned out that printing operations (this was a print server) had eaten up all the inodes so the "space" wasn't MB/GB/TB - it was lack of inodes. For most filesystems you can't increase inode allocation after original layout. If you have LVM in place you can create a new filesystem and migrate salvageable files to that. -----Original Message----- From: Ale <[email protected]> On Behalf Of Steve Litt via Ale Sent: Friday, January 2, 2026 2:41 PM To: [email protected] Cc: Steve Litt <[email protected]> Subject: Re: [ale] to lvm or not lvm is my dillema On Fri, 2 Jan 2026 14:02:37 -0500 Jeff Lightner via Ale <[email protected]> wrote: > +1 > > LVM makes life so much simpler when one runs into any kind of storage > allocation issue whether on a single drive or on a major disk array. Would life be even simpler than that if your entire disk contained only a swap partition and a root partition and didn't bother with LVM?
