    Question False Positive for Case-insenstitive filesystem for zxMig?

    Is anyone having issues with a false positive in zxMig tool when trying to set up a destination path in the Export Wizard?

    [zimbra@zimbra ~]$ zmcontrol version
    Release 7.2.7_GA_2942.RHEL5_20140314190150 RHEL5 NETWORK edition.

    zxmig is 1.8.18

    Error is "The path is on a case-insensitive filesystem."

    ---------------------------------

    First I mounted a USB drive which is a windows storage server 2008 R2 backup appliance.. I have been using this for normal ZCS Network edition backup for years with no problem.. So when I went into the Zextras zxMig tool in the Zimbra Admin GUI and put in /media/00coolnas/ferry I got "The path is on a case-insensitive filesystem". This was a surprise to me, I didn't know his was a requirement until then. So I figured that since this share is mounted as a windows cifs that it may be case-insensitive. So I changed plans.

    Second, I went ahead and created a nfs share on Server2 (RHEL 6 64bit) that I will be mounting on Server1 (server1 has zxMig). /media/nfs-ferry. Then went back to server1 zxMig and put in the new path and got same "The path is on a case-insensitive filesystem.". This cannot be true.. so I found instructions to test the file system.. here is the result:

    On Server1 (same server zxMig is on):
    [root@zimbra nfs-ferry]# mkdir Aa
    [root@zimbra nfs-ferry]# mkdir AA
    [root@zimbra nfs-ferry]# touch Aa/1
    [root@zimbra nfs-ferry]# touch AA/2
    [root@zimbra nfs-ferry]# ls
    Aa AA
    [root@zimbra nfs-ferry]# ls Aa
    1
    [root@zimbra nfs-ferry]# ls AA
    2
    [root@zimbra nfs-ferry]# pwd
    /media/nfs-ferry

    So it appears that zxMig is incorrect saying that my filesystem is case-insensitive... But I cannot proceed with the migration until this is resolved. It almost seems as it is stuck remembering /media/00coolnas Windows backup appliance and not seeing the new case-sensitive filesystem..

    What can I do now?

    Thank you.

    Hi Tim and welcome to our forums.

    As reported by bney on THIS thread yesterday, it seems that last zextras version (zxsuite/zxmig) has an issue with filesystem permission check. So if the zimbra user cannot write on destination path, the error is wrongly reported as a Case Insensitive filesystem.

    Our devs are investigating...

    Have a nice day.

    Oh!! I didn't even think of permissions issues as zimbra user.. now I feel dumb.. So it sounds like when Zimbra user can write to the destination path, I can most likely continue with the migration project... I'll go and fix the write permission... Thank you for the information.

    My problem went away when I gave zimbra user write permissions.. zxMig can now proceed. Thank you for your help.
