[LU-1667] setstripe, stripe size of 4G error is inaccurate.

• Status: Closed
• Project: Lustre
• Fix Version/s: Lustre 2.4.0
• Type: Bug
• Priority: Minor
• Reporter: Richard Henwood (Inactive)
• Assignee: Richard Henwood (Inactive)
• Resolution: Done
• Severity: 3

Description

The wording on the error message you get from setstripe -s 4G is inaccurate.

[root@centos62_vanilla ~]# lfs setstripe -s 4G /mnt/lustre
warning: stripe size larger than 4G is not currently supported and would wrap: Invalid argument (22)
error: setstripe: create stripe file '/mnt/lustre' failed
[root@centos62_vanilla ~]# lfs setstripe -s 4095M /mnt/lustre

More suitable wording would be stripe size of 4G or larger is not currently supported and would wrap.

• I might also question the value of the 'and would wrap'.

• Either the error is wrong or the check is wrong

  [admin@sjsc-6 admin]$ lfs setstripe -c 4 -s 4g stripe4_4g_chunk
  warning: stripe size larger than 4G is not currently supported and would wrap: Invalid argument (22)
  error: setstripe: create stripe file 'stripe4_4g_chunk' failed
  [admin@sjsc-6 admin]$ lfs setstripe -c 4 -s 4095m stripe4_4g_chunk
  
  if (stripe_size >= (1ULL << 32)){ rc = -EINVAL; llapi_error(LLAPI_MSG_ERROR, rc, "warning: stripe size larger than 4G " "is not currently supported and would wrap"); return rc; }
  

• Also note the error code returned should be re-evaluated as -22 may not be appropriate.

• This should be a trivial fix by correctly wording the error message:
  "warning: stripe size equal to or greater than 4G " ; With appropriate error code.
• After the change it would be ,

[root@osh-1 ~]# lfs setstripe -s 4G -c -1 /mnt/client/file.log
warning: stripe size equal to OR greater than 4G : Operation not permitted (-1)
error: setstripe: create stripe file '/mnt/client/file.log' failed
[root@osh-1 ~]#

Need to re-open this bug.
