Re: [Lustre-discuss] delete a undeletable file
If I run unlink .viminfo I got the same error: unlink: cannot unlink `.viminfo': Invalid argument I can't stop the MDS/OSS to do a lfsck or e2fsck because is a filesystem in production of a lots of terabytes Any idea more to delete the damm file?

Re: [Lustre-discuss] delete a undeletable file
You can move the entire folder (mv) to another location /lustre_fs/somthing/badfiles recreate the folder and mv back only the good files. If I run unlink .viminfo I got the same error: unlink: cannot unlink `.viminfo': Invalid argument I can't stop the MDS/OSS to do a lfsck or e2fsck because is a filesystem in production of a lots of terabytes Any idea more to delete the damm file?

Re: [Lustre-discuss] delete a undeletable file
The snarky reply would be to use Emacs. More seriously: When I see something like ?? in the attributes for a file, my first thought is that the group_upcall on the filesystem is not correct, so permissions are broken. If you can log on as root, you may be able to see it clearly. If that doesn't work, you may have to run an fsck on the MDT (which may take minutes to hours depending on the size of your MDT) If that doesn't work, follow the procedure for running an lfsck (which will take a long time, and require quite a bit of storage to execute) -Ben Evans From: lustre-discuss-boun...@lists.lustre.org [lustre-discuss-boun...@lists.lustre.org] on behalf of Alfonso Pardo [alfonso.pa...@ciemat.es] Sent: Thursday, March 07, 2013 10:09 AM To: lustre-discuss@lists.lustre.org; wc-disc...@whamcloud.com Subject: [Lustre-discuss] delete a undeletable file Hello, I have a corrupt file than I can’t delete.

Re: [Lustre-discuss] delete a undeletable file
Hi, If the file is disassociated with an OST which is offline, bring the OST back online, if the OST object it self is missing then you can remove the file using 'unlink' rather than 'rm' to unlink the object meta data. If you want to try and recover the missing OST object an lfs getstripe against the file should yield the the OST on which it resides. Once that's determined you can take that OST offline and e2fsck may successfully restore it. Another option as Ben correctly points out, lfsck will correct / prune this meta data as well as the now orphaned (if any) OST object. -cf On 03/07/2013 08:30 AM, Ben Evans wrote: The snarky reply would be to use Emacs.

Re: [Lustre-discuss] delete a undeletable file
You could just unlink it instead. That will work when rm fails. bob On 3/7/2013 11:10 AM, Colin Faber wrote: Hi, If the file is disassociated with an OST which is offline, bring the OST back online, if the OST object it self is missing then you can remove the file using 'unlink' rather than 'rm' to unlink the object meta data.
