[SOLVED] Persistent storage not working

jsteel · 2012-01-31 13:23:23

Hi,

I've found this [1] but it doesn't seem to be working for me. I specify either "cow_persistent=" or "cow_label=" or both and any changes I make (such as creating a file in /home/arch/) are not saved after a reboot (obviously specifying the same options again at boot time). Am I missing something or is there something else I can try?

Thanks

1. Is there enough space on your device/partition? What's your partition scheme and how exactly are you calling cow_label? I had the best luck just setting filesystem labels and using cow_label.
2. Are you copying files from /etc/skel to your home directory with the little script from the wiki? I made that mistake and it overwrites any changes in /home because that happens AFTER the persistent data is retrieved.

I think space was the issue. I used dd to copy the iso but it looks like it doesn't leave any breathing room. I simply created a fat partition on the rest of the drive and labelled that "cow", specified cow_label=cow and it looks OK now.

Many thanks!

FAT for COW is not a good idea. Such fs does not support sparse files, this implies a waste space.

ext3/4 then?

Also it says the default space for "Copy-On-Write files of dm-snapshot" is 75% of the partition. Is there any harm in using 100% if I don't need the space for anything else?

Thanks

Yes.

Please let me know where you read such thing. I guess you are confused with 75% of RAM for tmpfs, when no persistent is used.

Yes I was confused. Many thanks.
