Hi all, I have a quota problem with xfs (xfsprogs 3.1.7+b1 on debian GNU/Linux 7 -- wheezy) and samba-4.1.19. If I set a user quota to say 10GB, windows explorer reports a 20GB quota of which none used. If I change quota to x, windows explorer reports 2x space of which none used. So I assume samba is somehow getting (albeit incomplete and incorrect) xfs quota info from operating system. disks

Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

There are several places where ZONE_DEVICE struct pages assume a reference count == 1 means the page is idle and free. Instead of open coding this, add a helper function to hide this detail.

Hi Folks, Can you guide me about how to convert the CentOS file system from EXT3/EXT4 to XFS without loosing data? I have tried search in google about this but I couldn't get the relevant idea. ** -------------- next part -------------- An HTML attachment was scrubbed...

Hi, This might be a silly question: which would be the best inode ratio for a 5 Tb filesystem dedicated to Maildir++ storage? I use ubuntu server, which has a preconfigured setting for mkfs.ext4 called "news" with inode_ratio = 4096, and after formating the fs with that setting and then with the defautl setting I see this difference of space (wasted space, but more inodes): 4328633696

Hi, Everytime I restart Centos 7 I receive a error saying? metadata is corrupt and then I need to go through the process of mount and unmount the disk uuid then run xfs_repair {some uuid} or xfs_repair -L {some uuid} which ultimately corrupts even more. I?m running on a RAID 1 two identical drives this has happened more then once and had to reinstall. Any way I can prevent this when I

Hi All, I have a very strange problem that I'm unable to pinpoint at the moment. For some reason I am simply unable to get xfs_quotas to report correctly on a freshly installed, fully patched CentOS 6 box. I have specified all the same options as on another machine which *is* reporting quota LABEL=TEST /exports/TEST xfs inode64,nobarrier,delaylog,usrquota,grpquota 0 0 xfs_quota -xc

We're experiencing problems with some legacy software when it comes to NFS access. Even though files are visible in a terminal and can be accessed with standard shell tools and vi, this software typically complains that the files are empty or not syntactically correct. The NFS filesystems in question are 8TB+ XFS filesystems mounted with

we recently deployed some large XFS file systems with centos 6.2 used as NFS servers... I've had some reports of a problem similar to the one reported here... http://www.linuxquestions.org/questions/red-hat-31/xfs-inode64-nfs-export-no_subtree_check-and-stale-nfs-file-handle-message-855844/ these reports are somewhat vague (third indirectly reported via internal corporate channels from

Yes, I rm'ed the wrong directory. The disk has not been written to since, now mounted ro. Is it possible to recover the files without doing forensics on the whole partition? I know the UID and path. XFS is supposed to be pretty amazing, can I get it to do this? Thanks, Dave

I have a lot of people whispering "zfs" in my virtual ear these days, and at the same time I have an irrational attachment to xfs based entirely on its lack of the 32000 subdirectory limit. I''m not afraid of ext4''s newness, since really a lot of that stuff has been in Lustre for years. So a-benchmarking I went. Results at the bottom:

Hello, Do you have recommendations on EXT4 and LVM options for a 3TB file-system for mdbox? We currently use the mbox format on a XFS with poor performances since the update in v2.1 (Debian). We will switch to EXT4 to have the possibility of shrinking the file-system if needed (which is not possible with XFS), we currently have LVM partitions but with mdbox we will use LVM snapshots to

I'm sure many are running ext4 FS's in production, but just want to be re-assured that there are not currently any major issues before starting a new project that looks like it will be using ext4. I've previously been using xfs but the software for this project requires ext3/ext4. I'm always very cautious before jumping onto a new FS, (new in the sense it is officially supported

Hi! I?m about to migrate a system whith 5000 accounts whith (~ 500GB) from "postfix/courier-imap/maildrop/mysql" to a new hardware whith "postfix/dovecot/dovecot/mysql". I?ll make a separate partition (raid 1) for the mail spool (/var/spool/vmail) and want to now what type of filesystem to use on it to increase performance. I read that XFS is a good choice, but is not
