LVM2 in use, files are disappearing!
I'm running Fedora 15 with LVM2. The contents of whole folders are disappearing after a few days! I put a file somewhere and a week later the folder is cleaned out. If there's a large # of files, they don't necessarily all disappear at once.
Directory structures are left intact. There's nothing in Lost+Found. Running on an Acer Laptop. Have never had a problem like this before, but I always used ext3. I don't want to reinstall Fedora and use ext3, but the current situation is unnacceptable, even if everything is backed up. Anyone heard of this or have some advice? I usually hang closer to the newbie forums, so I'd appreciate any help you all can offer. sda1 is ext4 /boot 500MB sda2 is lvm2 /tmp 55GB Running df gets this: Filesystem 1K-blocks Used Available Use% Mounted on rootfs 48509808 11078976 36938200 24% / udev 991416 0 991416 0% /dev tmpfs 998876 340 998536 1% /dev/shm tmpfs 998876 648 998228 1% /run /dev/mapper/VolGroup-lv_root 48509808 11078976 36938200 24% / tmpfs 998876 0 998876 0% /sys/fs/cgroup tmpfs 998876 0 998876 0% /media /dev/sda1 495844 71556 398688 16% /boot /dev/mapper/VolGroup-lv_home 4708880 2039404 2430272 46% /home /dev/mapper/VolGroup-lv_root 48509808 11078976 36938200 24% /tmp /dev/mapper/VolGroup-lv_root 48509808 11078976 36938200 24% /var/tmp /dev/mapper/VolGroup-lv_home 4708880 2039404 2430272 46% /home |
files from which location are getting deleted and is ur root a lvm too because if thats the case then the system wont work neither will it work if ur home directory is deleting files at random
.. if u can be specific please |
it's two partitions on the same drive. All LVM2.
|
my mistake. partition #1 is ext4 (boot), partition 2 is LVM2. Within that partition #2, there are logical volumes. The only place there is a problem is with the largest volume, mounted at /tmp -- that's the one that loses files.

the /tmp directory is only for temporary files and normally its contents are being deleted during reboot. Do not store data inside that directory if you want to keep it. |
Thank you, a straight answer! It is set up that way because after installing Fedora 15 the volume was mounted at /tmp and /var/tmp -- which I found when I started filling the home folder and running out of room too quickly.
So I'm wondering if maybe I just don't know how to read what's below or if the volume is in fact mounted at /tmp and /var/tmp and I need to change that. I'm looking at the volume labeled lv_root that is most of my 60GB hard drive and df says it's mounted at /tmp. I will try making some new directories at / and move the files there. This thread probably belongs in the newbie forum, apologies...

probably solved
The files copied and, since there's enough room, the problem was my assumptions.
Thanks for the help. I'll wait a couple weeks to make sure no files disappear, then flag this thread as solved. Thank you Thank you Thank you! |
It is best to mount shares under /media or /mnt.
For example, /mnt/raid /mnt/share /mnt/cdrom Those folder names are arbitrary but you get the idea. You shouldn't mount a filesystem under any tmp directory (that includes /var/tmp) unless it is truly meant to just limit the size available for tmp. |
