Description

When running lfs quota -u <USER> <FS> on Sequoia, a couple users do not have any files in their directory but quota reports a bogus large value:

# lfs quota -u pjmccart /p/ls1
Disk quotas for user pjmccart (uid 8624):
     Filesystem  kbytes   quota   limit   grace   files   quota   limit   grace
         /p/ls1     913       0       0       - 18446744073709547865       0       0       -

# du -sh /p/ls1/pjmccart/
913K    /p/ls1/pjmccart/

# ls -alR /p/ls1/pjmccart/
/p/ls1/pjmccart/:

Using systemtap to print the obd_quotactl structure when the osc_quotactl function returns, I see odd values coming from two of the OSCs:

osc_quotactl: "ls1-OST0037-osc-c0000003c865a400": {.qc_cmd=8388867, .qc_type=0, .qc_id=8624, .qc_stat=0, .qc_dqinfo={.dqi_bgrace=0, .dqi_igrace=0, .dqi_flags=0, .dqi_valid=0}, .qc_dqblk={.dqb_bhardlimit=0, .dqb_bsoftlimit=0, .dqb_curspace=0, .dqb_ihardlimit=0, .dqb_isoftlimit=0, .dqb_curinodes=0, .dqb_btime=0, .dqb_itime=0, .dqb_valid=15, .dqb_padding=0}}

Specifically, the values of dqb_curinodes:

ls1-OST0074-osc-c0000003c865a400:dqb_curinodes=18446744073709551615
ls1-OST0038-osc-c0000003c865a400:dqb_curinodes=18446744073709551615
