[LU-9923] lmv does not propagate read page errors for striped directories

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Affects Version/s: Lustre 2.11.0
• Labels: dne3 lmv
• Severity: 3
• Assignee: Lai Siyao
• Reporter: John Hammond

Description

As noted in LU-9857, stripe_dirent_next() does not propagate errors from mdc_read_page() and lmv_direct_next() ignores the return value of stripe_dirent_next().

# lfs mkdir -c4 d0
# touch d0/f{0..7}
# lctl set_param fail_loc=0x80000105 # OBD_FAIL_MDS_READPAGE_PACK
fail_loc=0x80000105
# ls d0
f0  f2  f3  f4  f6  f7
# echo $?
0
