Re: page->index limitation on 32bit system?

2021-02-28 Thread GWB
Getting btrfs patched for 32 bit arm would be of interest, but I'm not suggesting the devs can do much more with that. In practical usage, we ran into similar difficulties a while back on embedded and dedicated devices which would boot btrfs, but eventually it was easier to put storage on nilfs2.

Curious instance here, but perhaps this is the expected behaviour: mount | grep btrfs /dev/sdb3 on / type btrfs (rw,ssd,subvol=@) /dev/sdb3 on /home type btrfs (rw,ssd,subvol=@home) /dev/sde1 on /media/gwb09/btrfs-32G-MicroSDc type btrfs (rw,nosuid,nodev,uhelper=udisks2) This is on an Ubuntu 14 c

Yep, and thank you to Suse, Fujitsu, and all the contributors. I suppose we can all be charitable when reading this from the Red Hat Whitepaper at: https://www.redhat.com/whitepapers/rha/gfs/GFS_INS0032US.pdf: << Red Hat GFS is the world’s leading cluster file system for Linux. >> If that is G

It is confusing, and now that I look at it, more than a little funny. Your use of xargs returns the size of the kernel module for each of the filesystem types. I think I get it now: you are pointing to how large the kernel module for btrfs is compared to other file system kernel modules, 833 megs

Well, now I am curious. Until we hear back from Christiane on the progress of the never ending file system shrinkage, I suppose it can't hurt to ask what the signifigance of the xargs size limits of btrfs might be. Or, again, if Christiane is already happily on his way to an xfs server running ov

Hello, Christiane, I very much enjoyed the discussion you sparked with your original post. My ability in btrfs is very limited, much less than the others who have replied here, so this may not be much help. Let us assume that you have been able to shrink the device to the size you need, and you

Michael, That's great news. Well done. ext4 works just fine for most cases. If you wish to experiment I might suggest more work on your part (just what you need, right?) by using btrfs for smaller file systems (perhaps just root, maybe /var, /bin etc.) but try installing zfs for large file syste

I don't expect accurate data on a btrfs file system when using df, but after upgrading to kernel 4.4.0 I get the following: $ df -i ... /dev/sdc3 0 0 0 - /home /dev/sdc4 0 0 0 - /vm0 ... Where /dev/sdc3 and /dev/sdc4 are btrfs file
