Experienced Personal Data Provider.The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a Chinese national scientific research facility operated by the National Astronomical Observatories, Chinese Academy of Sciences. It is a special reflecting Schmidt telescope with 4000 fibers in a field of view of 20 deg2
 in the sky. Until July 2017, LAMOST has completed its pilot survey which was launched in October 2011 and ended in June 2012, and the first five years of regular survey which was initiated on September 2012. After this six-year-survey, we totally obtain 9,026,365 spectra, which consist of stars, galaxies, quasars and other unknown objects[1−7]
. Now, the fifth data release (DR5) has published online (http://dr5.lamost.org/), and released data products include：

Spectra. - IIn general, there are 9,026,365 flux- and wavelength-calibrated, sky-subtracted spectra in DR5, including 8,183,160 stars, 152,863 galaxies, 52,453 quasars, and 637,889 unknown objects, and these spectra cover the wavelength range of 3690-9100 angstrom with a resolution of 1800[2−3]
 at the 5500 angstrom.
Spectroscopic Parameters Catalogs. - In this data release, six spectroscopic parameters catalogs are also published，and they are the LAMOST general catalog, the A, F, G and K type star catalog, the A type star catalog, the M dwarf catalog, the observed plate information catalog, and the input catalog respectively. In the LAMOST general catalog, it includes 36 columns of basic spectroscopic information, for example, right ascension, declination, signal to noise ratio, magnitude, classification and redshift, which are also provided by the A, F, G and K type star catalog, the A type star catalog, and the M dwarf catalog. These three catalogs also provide other parameters, for example, atmospheric parameters (effective temperature, surface gravity, and metallicity), spectral line indices, line widths, the metallicity sensitive parameter, and the magnetic activity flag. In addition, the observed plate information catalog mainly contains nine basic plate information for all published plates, and the input catalog includes 24 basic fields mentioned above and three new fields which are not included in above catalogs.

Hey @jacktree7.I see that you have completed this round of encapsulation and have a few questions for you .

1. Why the two SPs f03156617 and f03148356 were not disclosed in the previous application?
2. f03055005, f01315096, f01106668 have a low success rate in retrieval, how do you explain this situation?

[jacktree7]

1.Sorry, these two SPs were not updated in time. 3 weeks ago, the original SPs were delayed in the data storage process due to a temporary problem with filecoin pledged coins, so I temporarily found a partner to recommend these two new SPs, and I will continue to update them later. f03148356 Linyun Japan, f03156617 Tongkun Sydney. 2.f03055005, f01106668, f01315096 these SPs, I have contacted and communicated with them, they told me that they are studying the principle of Spark, and recently happened to run into the main network upgrade on August 6, it will be improved later. Please stay tuned.

[Marshall-btc]

Ok, I'll support this round, but still want you to contact SPs to improve retrieval success.

Hey @jacktree7 ,I see that overall Spark retrieval is good in your latest report, but please explain these 5 node Spark retrieval anomalies.

[jacktree7]

Thank you for the allocator operator's patient response. I have communicated with these clients, and I’m providing the information below:

1. The two nodes in the United States experienced network outages due to data center failures starting from October 1. During this period, the clients worked hard to restore the network. The screenshot shows the first penalty record 24 hours after the network went down at 3 AM on October 1. It wasn't until today that the client restored a standard 1G local carrier bandwidth, so normal network operations have just resumed, and the Spark retrieval rate will gradually improve in the future.

2. For the other three nodes, the clients reported that they are using the DDO mode. Currently, Spark and DDO are not fully compatible. Below is a screenshot of the DDO mode. We will try to minimize the use of the DDO ordering mode in the future.

Please review this information and continue to support 2PiB. Thank you very much！

[Marshall-btc]

Looks good, but for Allocator compliance operations purposes, I will be approving this round of Datacap cautiously, with limited intervention on the new batch quota, approving 2PiBs as per the rules, but this time only 1PiB at first.I will resume 2PiB quota approvals after subsequent improvements are seen.

@jacktree7 Please explain “The Client declared 6 replicas, while 8 of them already exist.” https://github.com/filecoin-project/Allocator-Governance/issues/216#issuecomment-2486404278

[jacktree7]

Hi @Marshall-btc 6 copies is the minimum, so some data will have more backups in order to have more secure redundancy for the data. Also, considering that some sp declared sector period is only 180 days, had to find more sp for storage in order to meet my data storage deadline.
